issue producing pdf from tex

[GoogleCodeExporter]

 I tried many time to produce the pdf example with "python demo_context.py", under the "examples" folder, but I always get an error.

I thought it was a bug, and I have wait months in order to see it fixed... but 
today I took a look at the source and I realize that in my debian squeeze is 
missing the "context" module!

If Relatorio don't find "texexec" executable it produce an "obscure" error 
message, look at here here:

$ python demo_context.py
generating output_basic.pdf...
Traceback (most recent call last):

    File "demo_context.py", line 12, in <module>

        content = report(o=inv).render().getvalue()

    File "/usr/lib/python2.5/site-packages/relatorio-0.5.5-py2.5.egg/relatorio/templates/base.py", line 36, in render

        return self.serializer(self.events)

    File "/usr/lib/python2.5/site-packages/relatorio-0.5.5-py2.5.egg/relatorio/templates/pdf.py", line 61, in call

    File "/usr/lib/python2.5/subprocess.py", line 457, in check_call

        retcode = call(*popenargs, **kwargs)

    File "/usr/lib/python2.5/subprocess.py", line 444, in call

        return Popen(*popenargs, **kwargs).wait()

    File "/usr/lib/python2.5/subprocess.py", line 594, in init

        errread, errwrite)

    File "/usr/lib/python2.5/subprocess.py", line 1153, in _execute_child

        raise child_exception

OSError: [Errno 2] No such file or directory

I propose to check if the "texexec" exists or to catch this error in order to 
explain the problem ("'texexec' not found" or similar)

Thanks
