ENVI 5.0 and OS X 10.8 installation

ENVI 5.0 requires additional packages not included in OS X 10.8 Mountain Lion.

Java – ENVI has required Java for years. The ENVI installer will prompt the user and download it as part of ENVI installation.

X11 – X11 is no longer included with Mountain Lion, but the installer will prompt the user to manually download X11 v2.7.2 or later from http://xquartz.macosforge.org

Installing X11 using the installer defaults seems to work for most users. v2.7.4 was tested and does seem to work.
