Error building LO - ("LIBO_UDK 4.4 not found")

Hi there,

I was building LO on GNU/Linux (on a machine where LO building went smooth
until a couple months ago) and I got this message ["SOMEPATH" is my
replacement of a longer path]:

DynamicLibraryManagerException: "Failed to load dynamic library:
SOMEPATH/libreoffice/workdir/LinkTarget/CppunitTest/libtest_sax.so
SOMEPATH/libreoffice/instdir/ure/lib/libuno_cppu.so.3: version
`LIBO_UDK_4.4' not found (required by
SOMEPATH/libreoffice/instdir/program/libuno_cppuhelpergcc3.so.3)"

Path is
'.:SOMEPATH/libreoffice/solenv/bin:/home/seriouspillow/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/lib/jvm/java-7-openjdk-amd64/bin'
[build LNK] CppunitTest/libtest_sot_test_sot.so

Error: a unit test failed, please do one of:

export DEBUGCPPUNIT=TRUE            # for exception catching
export CPPUNITTRACE="gdb --args"    # for interactive debugging on Linux
export CPPUNITTRACE="\"[full path to devenv.exe]\" /debugexe" # for
interactive debugging in Visual Studio
export VALGRIND=memcheck            # for memory checking

and retry using: make CppunitTest_sax

make[1]: *** [SOMEPATH/libreoffice/workdir/CppunitTest/sax.test] Error 1
make[1]: *** Waiting for unfinished jobs....
make: *** [build] Error 2

Any ideas?

_Maybe_ it's noteworthy that I'm trying to compile a branch whose last
commit is around 9 months old; just mentioning that for completeness.

I tried using "EXPORT DEBUGCPPUNIT=TRUE" and "make CppunitTest_sax" but it
produced no output after "[build CUT] sax" for around 30 minutes.

Cheers,
Matteo
