in reply to Apache, no suexec, suid and the environment

In *nix, LD_LIBRARY_PATH is commonly a colon-separated list of directories. If you do not wish to clobber existing directories, you may want to either append or prepend a path: 
$ENV{LD_LIBRARY_PATH} .= ":/my/new/path";   # append
$ENV{LD_LIBRARY_PATH} = "/my/before/path:" . $ENV{LD_LIBRARY_PATH};   
+# prepend

It is also a good practice to check if LD_LIBRARY_PATH is defined before doing this.

    Hi,
    thanks for pointing that out, but I am well aware of what LD_LIBRARY_PATH is, how it is used and what values it takes in the situation at hand. The problem is that the programs called from perl don't find their libraries in this suid-script and I can't see why not.

    Regards... stefan k
    you begin bashing the string with a +42 regexp of confusion
