ISPConfig no likey my PHP 5?

I'm setting up ISPConfig... got all of the necessary packages installed... then thought i was getting somewhere. Unfortunately, I hit a snag near the end. Here it is:

checking for MySQL UNIX socket location... no
configure: error: Cannot find MySQL header files under /usr.
Note that the MySQL client library is not bundled anymore!
ERROR: Could not configure PHP

ERROR: The PHP binary coming with ISPConfig does not work properly on your system! The installation routine stops here!

The only fatal error seems to be related to PHP. Now I installed PHP5 just before trying to install this; could that be the problem perhaps?

Any feedback would be appreciated; I'm new to Debian and working out of Adelstein and Lubanovic's "LINUX System Administration," so I'm not able to figure this stuff out freehand at this point. THANKS!

 

Awesome! Thanks for helping. I found the guide and bookmarked it for future printout. Thanks!
