''"We work around ..."'' != ''"We patch ...''", and the comment was in
"Special !Update/Build Instructions", not its "Patches" subsection.

remove that statement.

The comment referred to the following part of `spkg-install` (which is
still in, and presumably still necessary -- perhaps ask Dima, so should
have been kept):
{{{
#!sh
case "`uname -srm | tr ' ' '-'`" in
Darwin-9*-[Pp]ower*)
# Don't add debug symbols because configure otherwise
# fails due to a bus error in Apple's 'ld' when trying
# to determine if global symbols are prefixed with an
# underscore (cf.
http://trac.sagemath.org/sage_trac/ticket/5847#comment:35 ff.):
echo >&2 "Warning: Disabling debug symbols on MacOS X 10.5" \
"PowerPC because of a linker (?) bug."
echo >&2 "See

"ff. for details."
echo >&2

esac
}}}
By the way, the attached diff doesn't reflect the latest spkg version.
