Error installing sage from git on Cygwin64
The error message is:
FIND: Invalid switch /sage/src/bin/sage-env: line 434: /sage/local/lib/R/share/Makevars.site: No such file or directory
It seems that the packages ecm-6.4.4 and ncurses-5.9.20131221 failed to build. Does anyone know how to circumvent this?
