New description:

 After some head-scratching, I found that the configure script makes use of
 **ln**'s **-v** verbose flag. This flag does not exist in OpenBSD's
 version of **ln**. 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/
    ...

 }}}
