Issues with packaged programs

[Nathan Dehnel <ncdehnel@gmail.com>]

I have packaged "cadence" and its dependencies. There are a couple
issues with it, though.

-the ladish gui doesn't build because it can't find boost
-cadence builds, but errors with "python not found" when run

I was wondering if someone more knowledgeable could help figure it
out. It's attached below, and also hosted here:
