Yes, that's the problem: I thought that

  (patches (search-patches "ruby-taskjuggler-fix-TjTime.patch"))

was working the same as with other (origin...)s declarations but AFAIU
it does not work with "rubygems-uri"s

Oh OK, anyway that piece of code is useless since "after-unpack" there
are no more gzipped files... obviously they are already unpacked :-D

I'm new to gem's but after I've "manually" downloaded
https://rubygems.org/downloads/taskjuggler-3.7.1.gem I see that the
three files listed above are part of the gem file structure: I guess
ruby-build-system is trying to apply the patch before unpacking the *.gz
archives, but AFAIU it should do it after unpacking.

I'll try to study the code to see if I understand how it works
and if this is a bug, but unfortunately I've little time this days.

Thank you for your help! Giovanni
