bilogical has asked for the wisdom of the Perl Monks concerning the following question:

I was trying to install BioPerl in windows using ppm. The latest version available is BioPerl 1.6.1 on http://bioperl.org/DIST. When I tried to install it, a number of prerequisite modules were being installed too, which include Bioperl 1.4. Then an error message showed up:

“ERROR: File conflict for 'C:/Perl/html/bin/bp_aacomp.html'.The package BioPerl has already installed a file that package bioperl wants to install.”

It looks to me that BioPerl 1.6.1 had installed a file that bioperl 1.4 wanted to install again. I don’t know why bioperl 1.4 was one of the prerequisites for 1.6.1. If I just install 1.4, it will OK. But I need a newer version, because some modules (like Bio::Tools::HMM) is not included in 1.4.

I saw on internet that somebody had the same problem when he was trying to install BioPerl 1.5, but I didn't find the solution.

Anybody has a clue on that? Thank you for your time.
