hi all,
after being pointed to the "install_name" ld flag by Apple engineering,
Check the man page for ld under install_name - you'll see how libraries can
be linked with the full path to where they're ultimately going or not.
Clearly, in one case this happened, and in the other not.
i'd looked for install_name in the openssl 0.9.8 src, to no avail ...
but, given the above pointer, and doing a little checking ALSO in 0.9.7 src, i
find:
% ls temp/
openssl-0.9.7g openssl-0.9.7g.tar.gz openssl-0.9.8

NOTE: *no* instance of the "install_name"
iiuc, then, the 'issue' of incomplete install_name -- i.e., the missing
prepended paths -- lies in this stanza ... and it's a code bug in the latest
OpenSSL.
cheers,
