I have this error after upgrading openssl.
---
$firefox
/libexec/ld-elf.so.1: /usr/lib/libssl.so.4: Undefined symbol "EVP_idea_cbc"
---

openssl is openssl-beta-overwrite-base-0.9.8b_1

I have no multiple openssl installed (i mean no openssl libs in /usr/local..)

I notice that this link refers to the same problem without any solution http://www.bsdforums.org/forums/archive/index.php/t-20349.html

It's weird that a fresh firefox compiled from ports looks for libssl.so.4 and not .5 ....

I have no clues about how to fix this error.
