Morpho

I am trying to start morpho.

I have set my Paths as such:

desktop:~$ echo $JAVA_HOME
/usr/lib/jvm/java-6-sun

desktop:~$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/lib/jvm/java-6-sun/bin

but when I try to launch morpho using

./morpho-1.9.0/morpho

I get the following error

ls: cannot access ./lib/*.jar: No such file or directory
Using dynamic classpath: .:/usr/lib/jvm/java-6-sun/jre/lib/rt.jar

Could not find the main class: edu.ucsb.nceas.morpho.Morpho. Program will exit.

Not sure why this is happening, but I do have both java-6-sun and java-6-openjdk installed, and I get a similar error when setting either as the JAVA_HOME path.
