So, the setup() function in Macaulay2 (version 1.4, when I answered YES to
all questions) broke my sudo. It changed something in the DYLD
path/environment/library or something. I got this "dyld: DYLD_ environment
variables being ignored because main executable (/usr/bin/sudo) is setuid
or setgid".
Now, I completely uninstalled Macaulay2, including removing a bunch of
files in my home directory beginning with . Then I put a symbolic link to
M2 in my /usr/bin. Then I put back the -e that was in the macaulay2.py
files inside of Sage.
Now, macaulay2(2+2) returns 4 with no error.
Thank you everybody!
By the way, there is a confusing discussion in Apple's support website
about the dyld thing.
