TLDR: Don't install OSX 10.11 if you want to use Sage OSX 10.11 disabled DYLD_* variables for scripts, more precisely: If a script file begins with a shebang the DYLD_* environment variables are omitted from the set of environment variables passed to that interpreter. So that fundamentally kills the way Sage runs on OSX.
We either a) always re-set DYLD_LIBRARY_PATH in each bash or Python script that calls one of Sage's binaries, or b) give up on DYLD/LD_LIBRARY_PATH and switch to rpath/runpath. Which we should have done a decade ago but then nobody is listening to me ;-P Which also means: no relocatable binaries unless your system has a tool to rewrite the paths installed. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
