Also curious.
Hmmm, not that surprising, except that signal 4 is "illegal instruction",
not a segmentation fault (but perhaps Apple uses different numbers on
Darwin 8).
Did you
* rebuild ECLIB (with {{{./sage -f ...}}}) (depends on PARI)
* rename or copy the 4.5.3 directory?
As mentioned above, three extension modules do '''not''' get rebuilt
though they link against PARI (and depend on ECLIB).
In case you copied the directory to keep the 4.5.3 installation, the
linker on Darwin will '''first''' search {{{$SAGE_LOCAL/lib}}} of the
'''old''' Sage installation, and therefore link against the wrong PARI
library. You can export {{{LDSHARED}}} to prevent this (see above).
I'm not sure if the setting differs on MacOS X 10.4, so you could do:
{{{
sage: import distutils.sysconfig
sage: distutils.sysconfig.get_config_var("LDSHARED")
' (current setting) '
}}}
and set {{{LDSHARED}}} to what you see except the first {{{-L...}}} (and
export it).
Then force rebuilding ECLIB, touch the three Cython files listed above and
do {{{./sage -b}}}.

my whole comment went to /dev/null)
