Thanks Shawn,
Yes, I noted and tried the work around, but atos complains that my PPC
only binary file has no symbols:
2006-09-19 16:53:06.479 atos[7888] vmutils: no architecture found in
header /tmp/VectorWorks_ppc
Atos cannot load symbols for the file /tmp/VectorWorks_ppc
Although if I replace our Universal Binary's VectorWorks with this ppc
one (and rename it to VectorWorks), getting info on the .app shows that
it is PowerPC and I can launch it. So I know my lipo worked...Activity
Monitor lists it as PowerPC as well.
Anyone else have a suggestion?

Ug, well, we're not there yet - still using 2.2 while we wait for Apple
to fix a problem in the compiler for 2.4. Thanks for the heads up -
perhaps atos will be fixed by the time we can use DWARF.
Cheers,
Lyndsey
