Bus Error?


I tried to compile a simple TK/Ruby code using “ruby rubyscript2exe.rb
squarecalc.rb --rubyscript2exe-tk” and:
Tracing squarecalc …
Gathering files…
Copying files…
Copying TCL/TK…
Creating squarecalc_darwin …
and when I click on the squarecalc_darwin (the file it created)I get

Last login: Mon Mar 30 20:56:35 on ttyp1
/Users/stefan/Ruby/rubyscript2exe/squarecalc_darwin; exit
Welcome to Darwin!
CodrescuMac1:~ stefan$
exit/tmp/eee.squarecalc_darwin.2/lib/tcltklib.bundle: [BUG] Bus Error
ruby 1.8.2 (2004-12-25) [powerpc-darwin8.0]

[Process completed]

Any tips on how to not get this? Am I using too old of a version of
ruby?(version 1.8.2)
Or could this be a problem with my code, or the way im trying to open
file that rubyscript2exe created?
Or I highly doubt this but is that what this is supposed to do?
Please help, Thanks!!
