[Evolution] Compiling for x86_64

[William Murray <W J Murray rl ac uk>]

  Hello guys,
          I am trying to compile evolution on a FC6/x86_64 box. I never
tried 64 bit before. On 32 bit I have to pass:

with-openldap=/usr/lib/evolution-openldap

to the evo configure scripts. I change this
to /usr/lib64/evolution-openldap but somehow it seems to be ingnored.
I keep seeing /usr/lib/evolution-openldap/lib in the configure logs, and
then it is rejected. 
   Can anyone advise?
 Thanks.
         Bill
