I'm using the svn import script by Oliver Betz to retain file mtime upon initial import (http://svn.haxx.se/users/archive-2006-10/1345.shtml), but i'm getting some errors.  I'm hoping someone might be able to help me out.

when i run the script, i get the following error:
$ perl importWithMtime.pl
svn propset svn:date 2001-10-29T18:34:10.000000Z --revprop -r HEAD
svn: E175002: DAV request failed; it's possible that the repository's pre-revprop-change hook either failed or is non-existent
svn: E175008: At least one property change failed; repository is unchanged
svn: E175002: Error setting property 'date':
Repository has not been enabled to accept revision propchanges;
ask the administrator to create a pre-revprop-change hook
I do have a pre-revprop-change.tmpl hook in the repository.  It contains the code below.  I'm using VisualSVN 2.5.2 on a Windows 7 x64 machine with Cygwin Perl and TortoiseSVN.  Any help would be greatly appreciated!



$ cat pre-revprop-change.tmpl

# The pre-revprop-change hook is invoked before a revision property
# is added, modified or deleted.  Subversion runs this hook by invoking
# a program (script, executable, binary, etc.) named 'pre-revprop-change'
# (for which this file is a template), with the following ordered
# arguments:
#   [1] REPOS-PATH   (the path to this repository)
#   [2] REV          (the revision being tweaked)
#   [3] USER         (the username of the person tweaking the property)
#   [4] PROPNAME     (the property being set on the revision)
#   [5] ACTION       (the property is being 'A'dded, 'M'odified, or 'D'eleted)
#   [STDIN] PROPVAL  ** the new property value is passed via STDIN.
# If the hook program exits with success, the propchange happens; but
# if it exits with failure (non-zero), the propchange doesn't happen.
# The hook program can use the 'svnlook' utility to examine the
# existing value of the revision property.
# WARNING: unlike other hooks, this hook MUST exist for revision
# properties to be changed.  If the hook does not exist, Subversion
# will behave as if the hook were present, but failed.  The reason
# for this is that revision properties are UNVERSIONED, meaning that
# a successful propchange is destructive;  the old value is gone
# forever.  We recommend the hook back up the old value somewhere.
# On a Unix system, the normal procedure is to have 'pre-revprop-change'
# invoke other programs to do the real work, though it may do the
# work itself too.
# Note that 'pre-revprop-change' must be executable by the user(s) who will
# invoke it (typically the user httpd runs as), and that user must
# have filesystem-level permission to access the repository.
# On a Windows system, you should name the hook program
# 'pre-revprop-change.bat' or 'pre-revprop-change.exe',
# but the basic idea is the same.
# The hook program typically does not inherit the environment of
# its parent process.  For example, a common problem is for the
# PATH environment variable to not be set to its usual value, so
# that subprograms fail to launch unless invoked via absolute path.
# If you're having unexpected problems with a hook program, the
# culprit may be unusual (or missing) environment variables.
# Here is an example hook script, for a Unix /bin/sh interpreter.
# For more examples and pre-written hooks, see those in
# the Subversion repository at
# http://svn.apache.org/repos/asf/subversion/trunk/tools/hook-scripts/ and
# http://svn.apache.org/repos/asf/subversion/trunk/contrib/hook-scripts/
