Ok, I almost did it the way SBO did. But as all Salix packages put files into $pkgname-$pkgver, I did not put the sources into /usr/src/fpc-$pkgver, but instead into fpc-source-$pkgver. I didn't want to mess up the directory of the fpc package with stuff from another package. The symlink is from fpc-source accordingly.

Comments? Can I go ahead an push it?
164M extracted (15M compressed) BTW. So only install this bloat if you really, really need lazarus.
