Polluting Gentoo

Let it be noted that this is the first time that I polute my Gentoo box. That is, by installing something with ./configure && make && make install and stuff. I did it as I was trying to make GmailFS work here, through the instructions on this website (pt-BR). Apparently, it didn't, and now I don't even know how to remove the "low-level" installation garbage I ended up with. Does anyone?

I particularly prefer using convert -resample instead of convert -sample for creating medium-sized images that I publish in my photolog. I get better quality images. For thumbnails I guess -sample should work fine.

USB Mass Storage Digital Camera under Linux

Works for all Sony Cybershots, as far as I know. This howto is in Portuguese, though. If I find a good enough one in English I'll post the link. The part about mounting it would be nice to be included in /etc/fstab
