[Help-smalltalk] A problem with gst-convert (total newbie)

[Rafał Mużyło]

I must stress that I know nothing about smalltalk.

I found a program, a mcz package, that I wanted to test.
As far as I know it's written in squeak (well, the source file extracted
from the package).
When I try to run `gst-convert -f squeak <filename>` the result is:
Object: PackageLoader class error: Invalid argument Parser: package not
found

I only installed smalltalk for this program.
The program in question is 
DrGeoII-HilaireFernandes.113.mcz from
http://www.squeaksource.com/DrGeoII.html
There's a good chance it won't work anyway, as it seems that it's using
squeak gui, but the question for now is why gst-convert doesn't work.
And if you're willing to help, CC me, cause I turned off mail delivery.
