This means jc1 cannot find libgcj.jar. Since you did not specify a
classpath, it searches in a default location (${prefix}/share/libgcj.jar)
which is hardcoded into the executable.
Is there any chance you are running the wrong jc1? Could there be more
than one GCC installed on your system?
When I am debugging jc1, I generally start with "gcj -v ..." and
copy/paste the entire command, along with the path to jc1.
