Can't use 'defined(%hash)' (Maybe you should just omit the defined()?) at
/usr/lib/perl5/site_perl/5.22.3/mhamain.pl line 1565.
Compilation failed in require at /bin/mhonarc line 39.
There is an open bug report that includes a patch for this.
I see on mailing-list archives in 2014, the debian maintainer says he's
fixing a similar error without «howto fix it»
Anybody could help me ?
I hope this helps!
