Build with strace

   cd /home/dev/gub
   mkdir STRACE
   rm -f STRACE/* target/linux-x86/packages/guile* ; strace -v -f -ff -s 1024 
-o STRACE/TP bin/gub --fresh -k linux-x86::guile

Then use grep to search for the file in STRACE that contains the detailed trace 
of the failing program.

In that strace file have a look at the attempts to load libc.so.6, inspect 
LIBRARY_PATH and LD_LIBRARY_PATH definitions in the environment ... try to 
understand whats going on ...
