Yes, this is a major problem. Currently, my own software dependencies
are to other projects of mine and handled by svn:externals, but it would
be much nicer to have a system which handles versions and dependencies.
It seemed like ITT VIS was starting to build this system into the
Workbench, but they removed the whole thing in IDL 8.0.

Yes, this would be great.

Not that I know of. The closest we have ever had would be Eric Deutsch's
IDL Libraries Browser:

http://www.astro.washington.edu/docs/idl/htmlhelp/

But that hasn't been updated since 2000 and didn't automatically handle
dependencies, it just allowed searching through commonly used libraries.

I would be up for helping on this.
