THe issue with pango is perhaps subtle.

In a multilib environment, pango was one of about 6 or so packages that
had to change because of path collisions.

The fix was to create a per-platform directory.

How that directory is named, and how the path is determined, have nothing
whatsoever to do with the original problem that needed to be solved, i.e.
changing the path so that components were not clobbered in a multilib 

For example, the paths
could have been used ;-)
