Re^6: Disputation of g0n on the power and efficacy of XS

I fail to see what the problem is. Note that I wrote "test Module". Not "install Module". It means that dependencies get installed in your CPAN build area. If you're done, it's just a matter of removing the build area.

Wrong, wrong, and wrong again. If I run "test Module" through the CPAN module and Module depends on Module2, then Module2 will be installed into the installation area specified by my .cpan/Config.pm (or the main Config.pm, if that doesn't exist). That is the only way the CPAN module knows to satisfy a dependency.

So, set up a different installation area. How hard can that be?	[reply]

That is the only way the CPAN module knows to satisfy a dependency. I guess you have a different CPAN.pm than I have. Just did a test, tested a module with a dependency. It gets the dependency, builds it, runs its tests, does not install it, builds the module I requested for testing, prepends the directory it builded the dependency in to `PERL5LIB`, then runs the tests for the requested module. No installations happen. It's easily tested that it hasn't installed the dependency - if you repeat the command, it will fetch and build the dependency again. Here are the specifics I did: $ su - # Become root. $ chmod 000 /opt/perl/lib/site_perl # As root. $ ^D # Normal user again. No LWP and a whole lot of dependencies available. $ rm -rf ~/cpan/build/* # Clear cache $ perl -MLWP -e1 Can't locate LWP.pm in @INC (@INC contains: ...) $ perl -MCPAN -e'test "LWP"' ...
