I have figured out that dependency on libssl.so.6 and libcrypto.so.6 was coming from ldap library.

The issue is solved by eliminating ldap from libcurl dependencies. How libcurl uses ldap? I want to make sure that functionality we are interested in is not affected.

Thank you,
Alona

Subject: libcurl links to openssl libraries twice

Hello,

I rebuild libcurl with openssl1.0.0m in view of recent openssl security vulnerability announcement.

I linked dynamically and was surprised to see that libcurl links to two different versions of openssl: one that I specified, and another one found in the system:

/usr/local/curl72/lib> ldd libcurl.so

Thank you,
