I don't understand why you need that, except if your locally installed
version is older than the version in /usr/. Is that the case? Else the
second find_path won't execute if before that your locally installed
version has been found. Also note that those variables you use in
find_path are automatically cached and I don't think they should appear
in it.

Apart from that, you're iterating over all test versions, thats
unecessary.

Thats the only good change I see in the diff.
