Did you see try my compile tip 5 days ago on the mailinglist?
"
If anyone is having issues compiling pjsip with the new XCode 4.2 + iOS 5 GM,
I had to change the host in configure-iphone script on the following line:
./aconfigure --host=arm-apple-darwin9 --disable-floating-point $*
to
./aconfigure --host=arm-apple-darwin10 --disable-floating-point $*
Then run:
export CC=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-llvm-gcc-4.2
./configure-iphone
in order to make the pjsip library compile.
"
Best regards,
Even Andr?

There are apparently some expectation incompatibilities between the LLVM frontend and the GCC frontend. This means that if you manually specify the compilers, aconfigure believes that you simply cannot compile on the platform.
