PHP and openSSL issues

Hi,

I'm trying to use the echo-merchant payment gateway in an e-commerce store.
However the script that I am using demands that PHP be installed with
the --with-openssl option.

The host that I am using have installed openSSL on their webserver, and it
shows up under the cURL entry on phpinfo() as the right version but not
under the 'configure' options as --with-openssl, however it seems that they
have managed to install it in some way other than through a command line
option?... is this possible?

Could someone explain how it can be possible to install openSSL on a machine
and have PHP pick it up und cURL, but not under configure options.

Many thanks in advance for any help offered.

Yours confusedly
