Problems here:
1) the backticks are asking perl to run the setenv command, and then
substitue the stdout of that command (probably nothing) and send it to
system(). You need to lose the backticks.
2) setenv is a csh built-in, and backticks use /bin/sh (see perldoc perlop).
Hence, the error message you're getting.
3) system() runs commands in a subshell. Any changes to the environment made
in the subshell will not affect the environment of your perl script.
The solution is just to assign %ENV:
$ENV{MY_VAR} = "test";
