Installing Question

Hi, I am trying to run the configure command as: ./configure --with-mysql=/usr/include/mysql but I get the error that it can't find the mysql headers. I check and the header files are there in /usr/include/mysql I even re-installed the mysql-developer package. When I run the command: ./configure --with-mysql It seems to work fine, but at the end it tells me I am using the built in Mysql libraries and that I should be using the provided mysql ones instead (I can't remeber the exact message). Did the last configure command actually use the /usr/include/mysql header files and I should just ignore that last message? Thanks, Chris
