If you mean compile Gcl (2.6.7) with this configure line :

./configure --prefix=/usr --enable-ansi --enable-locbfd \
  --disable-dynsysbfd --disable-statsysbfd --disable-dlopen

it works. Now I would have enjoyed having to pass only 

./configure --prefix=/usr --enable-ansi --enable-locbfd

but the (quite enigmatic) eror message was :

Exactly one loader option must be chosen: dlopen=no statsysbfd=yes
dynsysbfd=no locbfd=yes custreloc=no

This could be modified, in my own humble opinion.

I don't remember Gcl being so hard to compile. But I think someone
pointed something about it : Gdb modifies some installed libraries, so if
you install Gdb BEFORE Gcl, you may encounter troubles. Can this be
confirmed ?

Djezus man, speak good english to me ! :-) What the hell is "backtrace
from the segfault" ??? A new hard rock tube ? ;-) To be more serious, I
don't know what to backtrace : do I need to run make through Gdb ?
