It works. You just missed a very important option:
% gcj48 --main=HelloWorld -o HelloWorld HelloWorld.java
Abort (core dumped)
% ./HelloWorld
% gcj48 --main=HelloWorld -Wl,-rpath=/usr/local/lib/gcc48 -o
HelloWorld HelloWorld.java
% ./HelloWorld
Hello, World!
As you can see, you had to add "-Wl,-rpath=/usr/local/lib/gcc48" (or
"-Wl,-rpath=/usr/local/lib/gcc47" in your case).
