Error at make : libdb-4.3.so: could not read symbols: File in wrong format

Hello list,

I'm trying to compile openldap v2.3.31 (same happens with v2.3.34), on a
FC6 _EMT64_ (I don't have the problem on a i386). At the make step, I have
the following error :

I googlised a little, and try to add --includedir=/lib64/ to the configure
step, but it doesn't change anything.

I did the following thing that made the make working :
- removed the /usr/lib/libdb-4.3.so symbolic link to /lib/libdb-4.3.so
- recreate a link to /lib64/libdb-4.3.so
Now compilation works, but I'm afraid that my system may be unstable,
because a lot of installed software uses that library, and may have been
compiled with the 32bits version.

Is there a way to force the build of openldap to use /lib64/libdb-4.3.so
instead of /usr/lib/libdb-4.3.so?

For info purpose :
