Hm, yeah, the code in the package is just:
AC_TRY_LINK(
[#include <log4cpp/Category.hh>
#include <log4cpp/CategoryStream.hh>],
[log4cpp::Category::getInstance("foo").errorStream() <<
log4cpp::eol],
[AC_DEFINE(SHIBSP_LOG4CPP,1,[Define if log4cpp library is used.])],
[AC_MSG_ERROR([unable to link with log4cpp, need version 1.0 or
later])])
so I don't see anything obvious that I can do to fix this in the package.
Autoconf doesn't seem to like the way that Ubuntu is adding the additional
linker flag.
