# After removing and recompiling the prebuilt lib the tests fail?
# For some reason the test suite is executing a slightly different gdb command
# then before, which is lacking the file name of the lib that was pre built:
# gdb: No symbol table is loaded. Use the "file" command
# This also happens outside of portage so it is not related to any *FLAGS
