Comment(by jhpalmieri):

 First, after doing
 {{{
 $ export LDSHARED="gcc -bundle -undefined dynamic_lookup"
 $ ./sage -upgrade ...
 }}}
 Sage starts without segfaulting.  However, it wasn't totally successful
 because eclib didn't get rebuilt (nor did most of the packages).  Every
 log file gets touched, typically with a message like {{{sage:
 eclib-20100711 is already installed}}}, but that's it.  It looks to me as
 though the upgrade path still doesn't have the right version of "install",
 either in SAGE_ROOT/spkg or in the scripts spkg (which I don't think
 matters for upgrading).

 Second, of course every package depends on sage_scripts because the script
 sage-spkg (for example) must be present.  But for upgrading, I don't know
 which ones really might depend on changes made to it.
