Nope, 10.5.8 as well as 10.6.2 or something like that. I've tried using the
built-in libssl and building my own by the results are always the same:

on SSL_load_error_strings, all of the locks are called, as well as in
RAND_load_file. After that, they're simply never called again.

Besides adding "threads", is there anything I should be adding to the
OpenSSL configuration line (although this is drifting a bit away from
curl-specific stuff, perhaps there's some magic combination I'm missing).

Will keep trying out various combinations of flags and the like. Any
recommendations of places I should start snooping to see what is happening?

Thanks,
