please don't add '.' to path blindly in the no-'/' case.
it isn't safe because PKG_PATH may not contain
current directory.

in addition, if you do pkg_add somedir/pkg (a relative path),
./somedir/somedir/pkg will be searched.
i think it isn't your intent.

path_prepend_from_pkgname and path_remove_first are
a little hackish, IMO. i think what to do is:
1. dynamically alloc a temporary pathhead instead of using
   one global PkgPath.
2. add a new temporary entry from pkgname to it.
3. then pass it to installprereq.
4. free a temporary pathhead.
