Request Help XBMC configure error message

Could some XBMC guru please help ? I
have downloaded xbmc 12.1 and when
I run the .configure script, I get the error
message, as:
configure: Using Python 2.7
checking for main in -lGL... yes
checking for main in -lGLEW... yes
checking for main in -lGLU... yes
checking for mysql_config... no
configure: error: Could not find a required program. Please see the README for your platform.

Could you please indicate what exactly
I need to do to get around this issue ?
Any hints, suggestions would be of
immense help.Thanks in advance.
