Subversion build

Hi all,

Has anyone seen any rpm's or instructions for building subversion on 
x86_64. I'm getting the following error when trying to build from source 
and, while I gather that something is trying to link against a 32 bit 
lib for expat, I don't know enough to know how to fix it.

OS is Ltd Edition 2005 X86_64

Any help much appreciated.

Error :

*** Warning: linker path does not have real file for library -lgdbm.
*** I have the capability to make that library automatically link in when
*** you link to this library.  But I can only do this if you have a
*** shared version of the library, which you do not appear to have
*** because I did check the linker path looking for a file starting
*** with libgdbm but no candidates were found. (...for file magic test)
*** The inter-library dependencies that have been dropped here will be
*** automatically added whenever a program is linked with this library
*** or is declared to -dlopen it.
/usr/lib/libexpat.so: could not read symbols: File in wrong format

Thanks,

Peter
