Note that you can't modify your caller's environment variables directly. If you write this in perl: 
$ENV{PATH} = "/home/abc/xyz/bin:$ENV{PATH}";

It will only affect programs you call from that perl script.

The standard way of altering your caller's environment is to emit shell code, and evaluate that: 

# my_env.pl
#!/usr/bin/perl
print q{export PATH=/home/abc/xyz/bin:$PATH}, "\n";

# and this is how you call it:
$ eval `./my_env.pl`
