My server is running Ubuntu 32-bit, just the processor is 64-bit...

Only Graham and I have currently access to that account...

Here are the current problems (with the guile build) in kainhofer.com:

address@hidden:~/gub$ ABI=32 make lilypond &> log
[...]
must rebuild[tools]: guile

 *** Stage: untar (guile, tools)

See `config.log' for more details.

In guile's config log there is some more information: 
[...]
configure:22123: checking size of char
configure:22425: gcc -o conftest -

configure:22428: $? = 0
configure:22434: ./conftest
./conftest: error while loading shared libraries: libltdl.so.3: cannot open

configure:22437: $? = 127

address@hidden:~/gub$ locate libltdl.so.3
/home/lilypond/gub/target/tools/root/usr/lib/libltdl.so.3
/home/lilypond/gub/target/tools/root/usr/lib/libltdl.so.3.1.4


So, apparently, ./conftest can't find the libltdl.so.3 any more (which it was 
linked against), since the tools directory is no longer in LD_LIBRARY_PATH...
It seems that while building (and of course also when running) all the tools, 
we still need the tools directory in the LD_LIBRARY_PATH...
On the other hand, when compiling/linking, the LD_LIBRARY_PATH pathes should 
be ignored to prevent linking to libraries in tools/ ... Hmm, to be honest, I 
have no real idea of the correct way to handle this!

Cheers,
Reinhold
