I tend to think the OP's system is misconfigured. 32-bit vs 64-bit
messup is one possibility.
Another way to continue investigating this is for the OP to try
compiling a short test program that includes the JPEG header, and see
if it compiles, and if not, what warning/error messages appear. The
log the OP sent says just
configure:12340: WARNING: libjpeg found, but not version 6b or later
which isn't very informative.
