What is the original issue you are trying to solve?
According to the above Debian bug report, I am guessing XORP failed
to compile on x86_64 machine with SNMP enabled.

Did you try to use the following commands:
       ./configure --with-snmp --enable-shared
       gmake clean
       gmake

The original text in xorp/ERRATA cited FreeBSD as one of the example
OS-es that have that problem. I just tried Ubuntu-7.10 on amd64, and
using --enable-shared fixed the problem for me.
Note that I used latest vanilla XORP code from CVS, including the
rev. 1.27 fix to the following file that I just applied:
