just found a link that might help :
http://stackoverflow.com/questions/1055671/how-can-i-get-the-behavior-of-gnus-readlink-f-on-a-mac

To sum up the solutions :
1) use python os.path.realpath
2) use C realpath (3)
3) use fink /sw/sbin/readlink -f
4) implement in bash

Someone already proposed 4) a while ago :
http://mailman.archlinux.org/pipermail/pacman-dev/2009-February/008147.html
I did not compare this bash implementation with the one found on stackoverflow.

The best might still be to see if there is any way to avoid using
realpath, like I did for repo-add back then. But maybe there is really
no way out for makepkg, I don't know.
