Re: Is dialog4ports built in/for releng/13.0 also supposed to work under main [so: 14]? It gets SIGSEGV in my context.

This is an indication that something is missing in dialog4ports which
is required by FBSD-14 but not FBSD-13.  I had a similar problem with
dialog4ports under FBSD-14 some weeks ago, because i had a really old
version installed.  After upgrading it using the pkg repositories for
FBSD-14 all problems, in particular garbled text, disappeared.

IIRC there were updates to ncurses in FBSD-14 fairly recently which
would explain the problem with old versions of dialog4ports.
