CG 11.5 Notes on builds with GUB

[Federico Bruni]

I'm using gub for the first time, just to find which packages might 
need to be added to LilyDev.
So far I found only gcc-multilib, needed to compile some 386 packages 
when running 'make bootstrap'.

I want to report two problems:

1. Ghostscript download page has changed:
http://downloads.ghostscript.com/public/

This is the change to be made on gub on github:

$ git diff
diff --git a/gub/specs/ghostscript.py b/gub/specs/ghostscript.py
index 5f4d166..2f9ee9a 100644

2. The path in this paragraph is misleading:


"""
Copy the tarball into ‘gub/regtests/’, and tell the build system 
that you have done this:

   touch regtests/ignore
"""

It should say "Copy the tarball into 'regtests/', and...'
