I tested it and it works ok.
Perhaps you made a mistake somewhere !?

I attached my current configure.ac - please give it a try. Don't forget 
'autoreconf' after changing configure.ac. After that I do
./configure
make clean
make

If libpsl is still detected, make sure you really uninstalled libpsl.
Also 'grep -i PSL src/config.h config.log', HAVE_LIBPSL should be unset in 
src/config.h.

Further steps include looking into config.log (search for psl) to see what is 
going on.

Shouldn't be too hard to find.
