I installed Net::Telnet but it stil gives me error like I haven't installed it.
I installed Net::Telnet via CPAN.
But if I start gqrx-scan:
$ ./gqrx-scan
Can't locate Net/Telnet.pm in @INC (you may need to install the Net::Telnet module) (@INC contains: /Library/Perl/5.18/darwin-thread-multi-2level /Library/Perl/5.18 /Network/Library/Perl/5.18/darwin-thread-multi-2level /Network/Library/Perl/5.18 /Library/Perl/Updates/5.18.4 /System/Library/Perl/5.18/darwin-thread-multi-2level /System/Library/Perl/5.18 /System/Library/Perl/Extras/5.18/darwin-thread-multi-2level /System/Library/Perl/Extras/5.18 .) at ./gqrx-scan line 11.
