Would the attached patch be OK? (the tex2lyx part is unrelated but
should not hurt).
The patch is for configure.ac, which I don't use :) I don't even have
autoconf-2.61 (only 2.59), which is needed to regenerate configure after
applying your patch. I guess, the patch would work...

What do you means by no effect? Really "no effect"? Could we get to
see the config.log?
Yes, no effect. The entire config.log is large, but here are the
Qt4-related pieces (I use /opt instead of the customary /usr/local on
this desktop):

It works here. Could it be a GNU make thing? What error do you get?
A .Tpo file being an invalid object or something -- the file was still
being written out by compiler, when linker tried to use it. These things
are hard to reproduce, because the races are won by different pieces at
different times :) And I really do have 4 CPUs.
