If I go under cmake and edit the Makefile to add "-fpermissive" to CXXFLAGS, 
this error becomes a warning and the build continues

is there a case sensitive filesystem issue?

Added "QMAKE_CXXFLAGS += -fpermissive" to Cosmographia.pro to fix the build 
error

MAIN_PATH = src/Main 
still not fixed at of 1 hour age svn update 616

The Eigen error *might* be fixed in the 2.0.16 version of the Eigen library. 
This is preferred to adding -fpermissive. I will take care of updating Eigen.
