Bug#641764: Don't start scilab "Could not load JVM dynamic library (libjava)."

[Jorge Ernesto Guevara Cuenca]

Package: scilab
Version: 5.3.3-2
Severity: grave
Justification: renders package unusable

Dear Maintainer,
When scilab is executed from terminal emlator return this message:

Could not load JVM dynamic library (libjava).
Error: libjvm.so: no se puede abrir el fichero del objeto compartido: No existe el fichero o el directorio
If you are using a binary version of Scilab, please report a bug http://bugzilla.scilab.org/.
If you are using a self-built version of Scilab, update the script bin/scilab to provide the path to the JVM.
The problem might be related to SELinux. Try to deactivate it.
Please also check that you are not trying to run Scilab 64 bits on a 32 bits system (or vice versa).

Scilab cannot open JVM library.

If I execute scilab with verbose 1, i obtain the next output

Then I export JAVA_HOME with correct path and scilab works.

export JAVA_HOME=/usr/lib/jvm/java-6-openjdk-amd64/

Thanks for the time, sorry for my english, and I hope that the report is correct
