Having issues installed the serial support for JEmpeg. I installed JEmpeg with VM support in /usr/local/JEmplode_2.0
The serial FAQ says to download and unpack comm.jar into the /jre/lib/ext dir, which in my case would be /usr/local/JEmplode_2.0/jre/lib/ext.
Then it says to download, unpack, ./configure, make, make install rxtx. I get the following error when trying to configure:

javac: error while loading shared libraries: libhpi.so: cannot open shared object file: No such file or directory
checking java.home Exception in thread "main" java.lang.NoClassDefFoundError: conftest

configure: error: Make sure java is in your path before running configure

I tried adding /usr/local/JEmplode_2.0/jre/bin to my bash path with still no luck.

Any ideas as to what i'm doin wrong/missing?
