This seems wrong.  Did your perl script have the correct "she-bang" line as 
the first line of the file: #!/usr/bin/perl ?  Did it have execute 

Like many parts of Debian, I'd expect this to be using run-parts or 
equivalent, which simply makes a C/system call to "exec()".  On Linux, exec() 
handles ELF executables with the +x bit and text files with a "she-bang" line 
and the +x bit.

(POSIX/SUS Note: a "she-bang" line inhibits any expectation of standard 
behavior; it makes the entire interpretation of the script system-dependent.  
On the other hand, exec() is not required to handle scripts at all; a 
compliant shell must handle the exec() failure and interpret the script 
itself, but exec() isn't just called by shells.)
