An updated GUB status:

   1: Graham informed me that he does not have the energy to do open-source 
work outside of his job these days.
   2: The version of make used in GUB needs a fix to be compatible with glibc 
2.27.
   3: The versions of glibc and glibc-core used in GUB need a fix to be 
compatible with make 4.x.y. (Frédéric Bron already mentioned that problem in 
septemter 2016 on lilypond-devel)
   4: The download link of libpng12 is broken.
   5: The download link of jpegsrc.v6b.tar.gz is broken.
   6: ghostscript really should be updated.
   7: GUB fails to correctly build the English documentation of the latest 
stable prerelease, up to now nobody understands why.

Even with fixes for the problems 2-5 mentioned above bootstrapping or using GUB 
fails to work on openSuSE Tumbleweed, openSuSE 11.3 and on the fedora-27 based 
LilyDev because of problems not mentioned above.

It would be nice to have a list of linux distributions that were/are compatible 
to GUB ... usually it's much easier to debug a broken system if you have a 
working starting point.
