Comment (by programmingkidx):

 I ran "sudo port selfupdate", then ran "sudo port install minetest". The
 result was the same:

 :info:build
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_devel_irrlichtmt/irrlichtmt/work/irrlicht-1.9.0mt4/source/Irrlicht/COpenGLDriver.cpp:2012:13:
 error: use of undeclared identifier 'GL_TEXTURE_CUBE_MAP_SEAMLESS'; did
 you mean 'OpenGLProcedures::TEXTURE_CUBE_MAP_SEAMLESS'?

 I am using MacPorts 2.8.1. I thought this issue had been fixed. Is there
 something else left to do?
