Re: Install Math::GSL in Ubuntu

if you haven't installed all the dependencies you could end up in problems.

http://rt.cpan.org/Public/Dist/Display.html?Name=Math-GSL
checkout the bugs reported, and if it relevant to you and not yet solved, better look for other alternatives or contact the author.

Thanks for your answers. What I did was to go through all dependencies (bottom up) to discover which of the dependencies is causing the problem. For example, for a dependency of Test::Class I get:
cpan5> install Devel::Symdump
Running install for module 'Devel::Symdump'
Running make for A/AN/ANDK/Devel-Symdump-2.08.tar.gz
Prepending blib/arch and blib/lib of 20 build dirs to PERL5LIB; for 'get'
Has already been unwrapped into directory /home/sagiv/.cpan/build/Devel-Symdump-2.08-HnrO85
Prepending blib/arch and blib/lib of 20 build dirs to PERL5LIB; for 'make'
Has already been made
Prepending blib/arch and blib/lib of 20 build dirs to PERL5LIB; for 'test'
Running make test
Has already been tested successfully
Running make install
Already tried without success

How can I figure out what the problem is? I went through the list of reported problems but I don't think it's connected to mine. Thanks!

I forgot to add that when I do try to install Test::Class I get the following output (sorry, a bit long):
cpan2> install Test::Class

This means that Test::Class fails its tests, and in a bad way. This seems to be because Test::More changed the texts it outputs: http://rt.cpan.org/Public/Bug/Display.html?id=47060.

If you feel adventurous, you can try force-installing Test::Class and hope that it's only the tests that are failing and not the module.
