LiyDev 4.1 + GUB fails lilypond test on my system

[Hans Aikema]

I decided to first try and get an operational GUB build before further 
trialling to get the same running in a minimal docker container…. so off I went 
as per the website with LilyDev (version 4.1; decided to go conservative as 
AFAIK I would need the unstable branch of Lilypond for success with LilyDev 
5.0) , installed in a VMWare VM (4CPU, 8Gb memory, 40Gb disk space)

I tried to cook the proper recipe:
a git clone of https://github.com/gperciva/gub
a download of regtests tarball for 2.18.2 & touch of the regtests/ignore
a make bootstrap
a make lilypond
blend it all with a lot of patience….

then the logs started showing errors and the lilypond-test came to a grinding 
halt:

cd ./out-test && 
/home/aikebah/gub/target/linux-x86/build/lilypond-git.sv.gnu.org--lilypond.git-master/scripts/build/out/run-and-check
 "dblatex  suffix-lyxml.xml" "suffix-lyxml.dblatex.log"

Please check the logfile suffix-lyxml.dblatex.log for errors

with a suffix-lyxml.dblatex.log containing

/usr/bin/python: /home/aikebah/gub/target/tools/root/usr/lib/libz.so.1: no 
version information available (required by /usr/bin/python)
Traceback (most recent call last):
  File "/usr/bin/dblatex", line 5, in <module>

ImportError: /usr/lib/i386-linux-gnu/libapt-pkg.so.4.12: symbol gzseek64, 
version ZLIB_1.2.3.3 not defined in file libz.so.1 with link time reference

Anyone a clue what the root-cause of this error can be? It would seem to me as 
a conflict between libz.so as compiled by GUB and the python on LilyDev….. but 
then I would expect LilyDev 4.1 itself to be broken as well and I did not see 
any signals that LilyDev 4.1 itself would not be able to properly build 
Lilypond master branch.
