Error in scilab compiled for amd64

[Christoph Korn]

Hello,
I have compiled scilab 5.0.2 for hardy amd64.

The sources and binaries can be found in this ppa:
https://launchpad.net/~getdeb.packages/+archive

You can checkout the sources by downloading the files:
https://launchpad.net/~getdeb.packages/+archive/+files/scilab_5.0.2.orig.tar.gz
https://launchpad.net/~getdeb.packages/+archive/+files/scilab_5.0.2-1~ppa1.diff.gz

tar xzf scilab_5.0.2.orig.tar.gz
cd scilab-5.0.2
zcat ../scilab_5.0.2-1~ppa1.diff.gz | patch -p1

The i386 packages run fine.

In amd64 scilab gives this error:

This is the /usr/share/scilab/etc/scilab.start file:

The output of some calculations is also odd:
