Comment(by leif):

 Replying to [comment:62 leif]:
 > On MacOS X, one should at the moment either do an "in-place" upgrade
 (without renaming the directory / copying the original installation) or
 follow the instructions given above (regarding {{{LDSHARED}}}).

 If one tests upgrading in a new directory (renamed or copied) on MacOS X,
 it should be suffient to do
 {{{
 #!sh
 export LDSHARED="gcc -bundle -undefined dynamic_lookup"
 }}}
 '''before''' running {{{./sage -upgrade ...}}} (with the upgrade path
 provided by Jeroen).
