please help with fixing port

[Marko Cupać]

Hi,

Some would say that net-p2p/linuxdcpp is not that important, but being
the only decent GUI nmdc/adc client in FreeBSD ports tree, I think it
deserves to be properly maintained.

Latest update broke this port. I have submitted bug report:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=190600

Unfortunately, the only suggestion was to try and fix the port myself,
as there is no maintainer.

I have almost no experience in maintenance of ports, and no experience
at all with compiler errors, inclusion of headers etc.

If someone would be so kind in helping me fixing this port, or point me
in the right direction, I would be very grateful.

Regards,
