Andy Tidball commented on XALANC-643:
-------------------------------------
I also ran into this problem, but on a default Ubuntu 12.04 (and 11.10) setup.
I would guess that Ubuntu is somehow using --as-needed by default because I'm
certainly not doing anything out of the ordinary on purpose. I don't know the
Linux dev environment well enough to know for sure, though. In any case, I
independently arrived at the same fix that Petteri Raty has already submitted a
patch for. If it doesn't still apply cleanly to trunk, it should be trivial to
update.
