cgi not working :(

[Ronnie]

hello, Warren help us set up redhat this past tuesday and today while
moving some scripts over to the redhat machine i noticed that the scripts
wouldnt work.  The script alias in the httpd.conf file is this (if i
remember right)

  ScriptAlias /cgi-bin/  /vars/www/cgi-bin/

which correct me if im wrong means i put the cgi files in the directory
vars/www/cgi-bin  but to view them i would look under

  http://someurl/cgi-bin/scriptname

I tried viewing the script but i kept getting the 500 error, so i compiled
my script and i got this error:
 
 (offline mode: enter name=value pairs on standard input)

install_driver(mysql) failed: Can't locate DBD/mysql.pm in @INC (@INC

Perhaps the DBD::mysql perl module hasn't been fully installed,
or perhaps the capitalisation of 'mysql' isn't right.

Im assuming this means that DBD is not installed so i download the dbd for
mysql from here:

  http://www.lynxafrica.demon.co.uk/dbi/    

but when i try and compile the perl file eventually it says that mysql.h
not found.  help!

sorry for the long email
