Hello Dovecot users!There seems to be a new dependency in some modules (eg, lib-storage, libdovecot-lda, libdovecot-ssl) on OpenSSL. In Dovecot 2.0, those modules didn't require OpenSSL, but 2.1 does.
For the linking process the path to the OpenSSL library isn't specified properly (SSL_LIBS). Dovecot fails to build if OpenSSL is in a non-standard path. (Haven't checked if SSL_CFLAGS isn't properly used as well.)
Example for lib-storage:
env SSL_CFLAGS="-I/usr/local/ssl/include" SSL_LIBS="-L/usr/local/ssl/lib -Wl,-R/usr/local/ssl/lib -lcrypto -lssl" ./configure --prefix=/usr/local/${DOVECOTVER} --with-ssl=openssl --with-ssldir=/usr/local/${DOVECOTVER}/etc/dovecot/certs

Without SSL_CFLAGS and SSL_LIBS but just PKG_CONFIG_PATH, it also won't work.
Help appreciated ... Andreas
