why wont sage build?
attempting to install sage (7.6) from source on fresh ubuntu (16.04 lts) install. attempting to build in /usr/local/sage-7.6. when i try make with sudo, it says i dont have privileges to move some file. when i try with sudo, it says i can build as root... not encountered this problemo before. pretty sure i have installed on pre-requisites and repositories...

If you would like to try to build Sage anyway (to help porting),
export the variable 'SAGE_PORT' to something non-empty.

also, i know everything is compatible, because i just had to re-install ubuntu on my machine, so i had sage, on this same machine and same os, working fine. i might have downloaded a binary originally though
You definitely don't want to build as root. Since you're starting from scratch anyway, why not do
make cleanand then try again?ok, i'll try that
ok, so i dont really know why that worked but it did, so if one of you would like to answer that so i can accept it... someone else may run into a similar problem
Converted to an answer, go ahead and accept!
