[sage-devel] Re: Can't build Sage with 2GB RAM anymore

[sage-devel] sage always executes the binary found in SAGE_ROOT

2015-04-19 Thread ggrafendorfer
Hi When I build a new version of sage in a separate directory, and then, while beeing in that directory, execute ./sage then the current "old" version of sage, which can be found in SAGE_ROOT is executed. E.g., this looks as follows: .../data/sage-6.6$ pwd /mnt/data/sage-6.6 .../data/sage-6.6
