Just to clarify (thanks to Xavier), it worked on BSD but not in OSX which
does not have either "readlink -f" or "realpath"...
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.
Well, one way to avoid all this is to add something like:
[[ $PKGDIR == "." ]] && $PKGDIR="$startdir"
before we preserve the environmental variables. But that is bad as
things like PKGDIR="../" would still cause issues.
So I think we should just add the bash implementation of realpath as a
function inside makepkg. The one at stackoverflow is very simplistic so
I will take another look at the one posted to the mailing list. We
should really look at libifying some/all of this sort of stuff out of
makepkg...
