>Description:
The devel/libslang2 is bound to termcap. The FreeBSD implements tinfo, so the libslang2 can't use termcap at all on this OS.
>How-To-Repeat:
Install software that depends on the libslang2 (I found it on the sysutils/mc), note issues when working with terminal.
>Fix:
The following quick patch fixes the issue for me, but a graceful termcap detection may be introduced (please see the .else).
