LD_LIBRARY_PATH works for me.
It ought to work for you too.

    creche. gcj --main=HelloWorld -o HelloWorld HelloWorld.java
    creche. ./HelloWorld
    ./HelloWorld: error in loading shared libraries
    libgcj.so.1: cannot open shared object file: No such file or directory
    creche. LD_LIBRARY_PATH=/x1/egcs/install/lib ./HelloWorld
    Hello World!

(I configured both packages with --prefix=/x1/egcs/install)

Otherwise you can try use -rpath when you compile:

    creche. gcj --main=HelloWorld -o HelloWorld HelloWorld.java -Wl,-rpath,/x1/egcs/install/lib
    creche. ./HelloWorld
    Hello World!

Or you can add /usr/local/lib to your ld.so cache using ldconfig.

Or you can link statically, though this doesn't always work.
