Whilst test-rebuilding packages for the next perl release we found
an unrelated build failure:
Checking for liblog4cpp...
Cannot continue since you don't seem to have log4cpp installed
Please install the log4cpp-dev package and run configure again.
make: *** [debian/rules:11: override_dh_auto_configure] Error 2
The full log is here:
This seems likely to be caused by the new release of log4cpp 1.1.3-1
