Ok, from your information, i would assume you use the Oracle proc/c
precompiler on some AIX machine to link and build some program that uses
libcurl via the IBM xlc compiler.

As you set /usr/include/curl as include path which is outside the
typical oracle install location, there should probably a similar -L<path
to your libcurl.a> file somewhere.

It has probably nothing to do with Oracle 11 vs 10, but all with the
machine on which you build. So check if you have any libcurl installed
and adjust your link path.
