Actually it looks like the problem is exactly that apr-config --cflags
etc is *not* exporting the -D_FILE_OFFSET_BITS=64 flag; it is used when
building APR/httpd, but then is not picked up by mod_perl.  So the cause
of the problem is exactly the reason why mod_perl can't detect it. :(

I'd not be desperately unhappy to make APR 0.9.x refuse to build in this
configuration, but it would needlessly annoy those users who *do* know
what they're doing at the expense of those who don't.  Not sure what's
best to do.
