Re: [gentoo-dev] Perl, CPAN and modules

[Michael Cummings]

Hey there Dar,

	Wish I could give you the solution; unfortunately, I have a rather long bug going on on bugz regarding the sdl problems with perl. As an aside, portage isn't "smart" enough to check to see if you have manually installed your perl modules, so if you install something that depends on a perl module, portage will trot over, grab the ebuild for it, and emerge it - even if you already installed it yourself.
	Your problems with the pathing are related to the MakeMaker that came with perl5 (or should be - that's what determines where your module gets installed in the make phase).
	Also, when you unmerged perl, you wiped all of your installed modules - but portage doesn't know that. So it thinks your perl module dependancies are already met, even if they aren't.

	Are you by chance running gcc 3.2? I've noticed a trend on my own systems that the 2.95.3 boxes have no problem with sdl in frozen bubble, but the 3.2 box has the exact same issues as the bug. Just curious on the last bit, pulling at straws here. I'm more than welcome to any hints anyone else on the list might have,
