configure: error: Invalid BTLS platform
===>  Script "configure" failed unexpectedly.
Please report the problem to [maintainer] and attach the
"/wrkdirs/usr/ports/lang/mono/work/mono-" including the
output of the failure of your make command. Also, it might be a good idea to
provide an overview of all packages installed on your system (e.g. a
/usr/local/sbin/pkg-static info -g -Ea).
*** Error code 1
