Any environment variable set with setenv.add-environment for a mod_fastcgi server has its environment variable name stripped of any non-alpha characters. This makes it impossible to pass PERL5LIB to a perl fastcgi script on a per-request basis.

To illustrate:

 "LAB01_CONTEXT_CONFIG" => "/app/run/Machine/conf/development.config",
 "PERL5LIB"             => "/app/run",

Those variables become {{{LAB@_CONTEXT_CONFIG@ and {{{PERL@PERL_LIB@, which they should not.

This patch (against 1.4.8, but it should apply cleanly to svn) fixes the problem:
