55 OS unsupported: Headers or libraries not found for a supported GUI
57 Sorry, I can't find headers or libraries for a supported GUI
58 You need to install development headers and libraries for your GUI
59 For Win32: Platform SDK or a substitute
60 For X11: X11 headers and libraries, eg. the libX11-dev package on Debian
61 For OS X: Install Xcode
