Description:
------------
The test program compiled by configure links to a non-existant mysqli 
library (and fails to be run). See the following debug.log:

The dyld *does* exist at this location:

mysql_config gives this:

This problem exists in the latest v5 CVS snap and 5.2.3, but not in 
5.2.0.

Reproduce code:
---------------
 ./configure  --with-mysqli=/usr/local/mysql/bin/mysql_config

Expected result:
----------------
Configure should end like this:
