Description changed by klomeli:

Old description:
...
After some head-scratching, I found that the configure script makes use
of the **-v** verbose flag. This flag does not exist in OpenBSD. It was
causing the build process to fail due to some files not existing during
the compilation process.
I'm getting around this by removing all **-v** occurrences as a pre-
compilation step:
{{{
find . -type f | xargs sed -i -e 's|^ln -f -v |ln -f |'
}}}
To make the process a little smoother for other folks, perhaps creating
an alias that is conditional based OS type at the header of the script
along the lines of would be best:
{{{
case "$build_os" in
   openbsd*)
      alias mksymlnk="ln -f"
      ;;
   *)
      alias mksymlnk="ln -f -v"
      ;;
   esac
...
mksymlnk utils/fs/fs.* utils/lndir/
   ...
}}}
