Ok... in our codebase our Perl code calls to a dynamic link to get to perl so we can point it to a different version whatever whenever we want... that's fine...

I find, however, that I want to change which perl I am executing only for my sandbox so I can work on switching codebase from perl 5.6.1 to 5.8.3 while allong everyone else to go on their merry way.

It occurred to me that I should be able to replace the dynamic link with a perl or shell script, or C program that could choose which perl to run based on an environment variable that gets set for sandbox code already.

I tried the following:

Wrapper 

#!/prod/gnu/bin/perl

exec '/prod/gnu/bin/perl', @ARGV;

Caller 

#!/home/ant/test/perl

print "Hello world\n";

[download]
I get 
[ant@gums2-sun]$ ./test2.pl
./test2.pl: print: command not found

[download]
What am I doing wrong.. or stupid? Worse comes to worse I can search replace all the shebang lines... but I'd like to avoid that. Not really worried about efficiency, this is just temporary.
