Yes, this is what I suspected.

It is unfortunate that this bug happens.  In a perfect world that would not
have been the case.  I mean, since octave3.0_3.0.1-6lenny2 depends on
libglpk0 >= 4.29, the Octave binding for GLPK must work with libglpk0_4.35-1
(the version in experimental) but it doesn't.

The problem arises because since version 4.32 of GLPK, the __glp_lib_*
symbols are not exported anymore.  As Andrew Makhorin explained in a message
to bug-glpk [1], those symbols have never been part of the published API.
He then removed them form the list of exported symbols without bumping the
SOVERSION of the library.

Now, both 3.0.4 and 3.1.51 packages in Debian fail with the libglpk0 package
in experimental.  The problem seems to have been fixed in Mercurial [2] and
we should backport it to our packages before they migrate into unstable.
