There’s a number of packages out there that assume you are using the GNU versions of ls, wc, and so on. However, you aren’t when using a BSD system. Pkgsrc has historically dealt with this when GNU tools are needed for a package by prefixing them with a ‘g’. ‘ls’ becomes ‘gls’, and so on. Aleksey Cheusov proposed a fix to keep these utilities under their original names, which I think will go into the next quarterly pkgsrc release.
