If you are encountering an error when building the Stomp extension:
pecl install stomp
OpenSSL install prefix (no to disable SSL support) [/usr] : /usr
configure: error: Cannot find OpenSSL's libraries
ERROR: `/var/tmp/stomp/configure --with-openssl-dir=/usr' failed
Even when openssl-devel is installed on the machine, try answering 'yes' to the openssl path prompt:
pecl install stomp
OpenSSL install prefix (no to disable SSL support) [/usr] : yes
