>Description:
I recently became aware that INSTALL_ICONS is set in this port that I took over. INSTALL_ICONS appears to be a very Gnome-specific instruction to ensure icons appear in Gnome's menu.

Setting INSTALL_ICONS pulls in a lot of Gnome-specific ports that are not necessary for the correct functioning of Merkaartor.

Ofcourse, if you do use Gnome, setting this would be desirable, so I set INSTALL_ICONS if ${LOCALBASE}/bin/gnome-session is present on the system

I don't know why the diff-output touches the boost line, but it doesn't look to hurt either.
>How-To-Repeat:
Start in an empty FreeBSD environment, start the Merkaartor build and watch it pull in a lot of gnome stuff
