dnsrend 0.08 (new formula)

dnsrend is a DNS message dissector, showing excruciating detail to diagnose
malformed message contents.
That's actually what I did, but the point is that perl ignores PERL5LIB if -T is given. And the "dnsrend" script specifies -T in the hashbang, so the approach used by mytop (which inspired me at the beginning, but didn't work) fails.

There are two solutions:
1) remove the -T, and let the script run in non-taint mode. This equals to disable a security feature that has been explicitly enabled by the developer, and therefore undesirable.
2) Add explicitly -I/path/to/perllib to the invocation of the script. I can do that in the hashbang itself (which is what I did), or in the wrapper script in /usr/local/bin. Doing this in the wrapper script would not work if we call the script directly from $bin/dnsrend .
