 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/
    ...

 }}}
