What linux distro are you using? On some distros you can fix this problem by doing a symlink of the libcrypto library you have installed.
Please look the last question in the [url=http://www.fop2.com/documentation-faq.php:1mn9l2uw]FAQ[/url:1mn9l2uw] for the exact command to use for Centos 6.
A similar command can be used on Fedora or other distributions, but I cannot tell you exactly the command to use because the library you might have installed could be a minor revision up or down.
