This suggests that the library needs to be linked with
"-lz -lgcjgc" to eliminate this problem. Also, the
shared lib, /usr/lib/libgcjgc.so.1, shows undefined
non-weak symbols as well...
ldd -r /usr/lib/libgcjgc.so.1
libpthread.so.0 => /lib/libpthread.so.0 (0x0fbc0000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x6ffd4000)
libc.so.6 => /lib/libc.so.6 (0x0fe80000)
/lib/ld.so.1 => /lib/ld.so.1 (0x08000000)
undefined symbol: dlopen
which indicates it needs linked with "-ldl".
