Is that no the culprit? Well, I was expecting configure to find and use libssl, and state '--with- openssl: yes' when it finishes. Explicitly specifying 'with-openssl=yes' does not help : ./configure --prefix=/usr --with-openssl=yes checking for openssl/ssl.h... yes checking for SSL_library_init in -lssl... no configure: error: cannot find the ssl library I worked around it by modifying configure as stated above; libssl and libcrypto are linked in afterwards. Thanks.
