I too am having problems with this. Fresh avr-libc-1.2.3 does
not build or install files for the mega48 (and others like mega88,
I suspect.)

Any suggestions ?

I don't even see configure trying to test for mega48 support, as it
does for tiny13/tiny2313 support.

avr-gcc is 3.4.0, binutils is 2.14, both with patches from savannah to
support the extra targets.
