Currently the euse command uses the "readlink -f" command that does not work on non-GNU systems. An alternative is to use app-admin/realpath as done by eselect which works on other systems too.
readlink -f rocks++; Please don't add new deps to gentoolkit unless we are actually one of these systems that lacks gnu-coreutils
I suppose it can be a || ( app-admin/realpath sys-apps/coreutils ) dep like for eselect and selected the right one either at runtime or at installation time.
Created attachment 84988 [details, diff] gentoolkit-0.2.2_pre4-realpath.patch Proposed patch that might work as intended. Also, the dependency can add sys-freebsd/freebsd-bin to the list as that package provide a /bin/realpath already.
Hmm, it just made me remember the portage's quickpkg, which has the same issue for us: quickpkg: x=$(readlink -f $x)
Fixed in subversion revision 307
This was fixed with the release of gentoolkit-0.2.3_pre2.
