oops...  I've rebuilt Qt so many times with different configurations I
forgot to do it with the right compiler.  I'll try that in the morning when
I get back to the office.

I was compiling our app statically to make it easier to deploy - 1
executable instead of packaging with a bunch of libraries.  I'm sure our
actual software will be a bit bigger than the 14 megs though.  Perhaps it
would be easier on system resources on the gumstix if it was dynamic?  I'm
not used to embedded development where resources are limited.
