Perl 5.20 in FreeBSD
Message from perl5-5.20.3_8: The /usr/bin/perl symlink has been removed starting with Perl 5.20. For shebangs, you should either use: #!/usr/local/bin/perl or #!/usr/bin/env perl The first one will only work if you have a /usr/local/bin/perl, the second will work as long as perl is in PATH.
As an aside, the dependency list on the Perl5 FreshPorts page is among the most impressive I’ve ever seen. 6000+ packages require it to run, and as many to build.
