Chris Williams - 04/Jan/08 11:19 AM Checked in a first cut at this which supports resolving a single path variable (like GEM_LIB) to multiple possible paths/locations. It then will iterate through the locations and find if the resulting expanded path actually exists, returning the first one that does. What this does is allows us to have multiple gem install paths, but use the same variable to refer to both. Then we can resolve them to their correct file system paths regardless of whether there's one or 20 possible install paths (so long as the gem is installed). This also means we're still portable across different machines.
