Subject Re: build failure when try to install Mahout 0.2
Date Fri, 09 Jul 2010 09:16:09 GMT
I'm not sure about that particular failure, but, version 0.2 is very
old. Version 0.3 is also released, but, it is best to use the latest
version of the code, which will become 0.4, from Subversion. I know
this does not fail in the latest code.
