Hi, just letting you know that mac compilation seems to be very painless. I already had gtk installed through MacPorts and the the other library was on macports as "libticalcs2". From there I only had to ./configure, make and make install. It seems to have installed in /usr/local and booted in X11 with the command "tilem2". All seems to be working.
Glad to hear it !
Thank you for your feedback :)
