Your problem appears to be one with the she-bang (#!) line of your script. I can tell this because apache's claiming the exec is failing with "No such file or directory", which is a sign that the kernel is not finding the program specified on the she-bang line of the script. (An error exec'ing means that the perl interperator couldn't be run, so the problem can't be anything in the actual perl code.) I can see two scenerios:

• /usr/bin/perl is not the perl interperator.
• You have a stray \x0D (AKA carriage return AKA \r) at the end of each line of the script, so the OS is trying to run the file named /usr/bin/perl\x0D to run your script, which doesn't exsit. This would probably be caused by uploading your file without translating newlines from Windows. It can fixed on the (UNIX) command line with the one-liner perl -pi -e'tr/\r//d' file.

To test if your problem is one of these see if your script executes on the command line with ./perl_select_gebr.pl. If this returns an error, then you probably have one of those problems. Similarly you can test if you have fixed one of these problems from the command line by seeing if the same works. (update: previous sentence re-worked to actually mention testing fixes, as I meant to say originally.)

A side note: It's a good idea to use strict and warnings. And -T.
