Build transmission with gtk+ support

[User Roberth]

Hello, anyone sucsessfully installed transmission with gtk+ support from
ports?

[root at Magda /usr/ports/net-p2p/transmission]# make install clean
You may specify the following on the command line:
 
WITHOUT_OPENSSL=yes to disable OpenSSL support, using built-in SHA1
implementation. Warning, it is a bit slower if you use this option.
===>  Vulnerability check disabled, database not found
===>  Extracting for transmission-0.82
=> MD5 Checksum OK for Transmission-0.82.tar.gz.
=> SHA256 Checksum OK for Transmission-0.82.tar.gz.
===>  Patching for transmission-0.82
===>  Applying FreeBSD patches for transmission-0.82
===>   transmission-0.82 depends on executable: gmake - found
===>  Configuring for transmission-0.82
System:  FreeBSD
OpenSSL: yes
GTK+:    yes
Daemon:  disabled

Now use GNU make to build Transmission.
It may be called 'make' or 'gmake' depending on your system.
===>  Building for transmission-0.82

*** Error code 2

Stop in /usr/ports/net-p2p/transmission.

Only thing I've done to the Makefile is to enable gtk+ on compile
options.
