Subject FYI - version checking against libressl - FYI (not yet a bug)
Date Fri, 10 Apr 2015 19:26:54 GMT
I am experimenting with libressl - and just thought I would mention an
error message I am getting with regard to openssl compatibility

And if this has already been reported - please ignore - and accept my
apologies. I have not scanned the maillist for a previous report.

configure: WARNING: Your APR does not include SSL/EVP support. To enable
it: configure --with-crypto
configure: WARNING: OpenSSL libraries are unusable

Now there are differences between OpenSSL and LibreSSL - so you may need to
be thinking about different tests for testing OpenSSL API suitability.

>From config.log - some additional feedback.
