I found it:
The configure script of curl checks for ssl usability.
1) If it does not find the ssl header files, it disables the ssl feature in
   the lib, but not in the curl-config.
2) It does not look for the openssl headers in /usr/local/ssl as stated.
   I've set a link in /usr/include to /usr/local/ssl/include/openssl.
   That did the trick.
