Display error instead of "Internal Server Error"

Is it possible to tune the apache to display the real error from error_log in a CGI/PHP/Whatever file instead of "Internal Server Error" ?

Generally customer open a ticket saying that is problem with the server, 99% of the times its fixable if he goes to his control panel and look through error_logs.
I would like to show something like:
"Permission of this file is wrong, please change it to 755 and reload this page"

Thank you.
