resulting on the following FTBS for ganglia monitoring on recent versions of
DragonFlyBSD (confirmed with 2.4.1 and also

libtool: compile: gcc -std=gnu99 -DHAVE_CONFIG_H -I. -I.. -I.. -I../../include -g -O2 -Wall -MT metrics.lo -MD -MP -MF .deps/metrics.Tpo -c metrics.c -fPIC -D PIC -o .libs/metrics.o In file included from /usr/include/rpc/rpc.h:73,
from ../libmetrics.h:14,
from metrics.c:36:
/usr/include/rpc/pmap_prot.h:89: error: redefinition of 'struct pmap'

the problem isn't specific to ganglia though as it comes from a conflict
from the system headers :

/usr/include/machine/pmap.h (pulled from sys/user.h)
/usr/include/rpc/pmap_prot.h (pulled from rpc/rpc.h)

FreeBSD has also a similar problem which is worked around by removing that
header and their dependents from the include before including <sys/user.h>

#define _MACHINE_PMAP_H_
#define _VM_MAP_
#include <sys/user.h>

and as a similar workaround the following has been implemented for DFBSD

* XXX: HACK HACK HACK - avoid including machine/pmap.h and things that
* depend on it to avoid collision with struct pmap in rpc/pmap_prot.h
#define _MACHINE_PMAP_H_
#define _VM_VM_MAP_H_
#include <sys/user.h>

this problem was introduced around release of 2.4.0 as previous releases
didn't have any conflicts.

Since this bug report was opened we've changed from pkgsrc to a custom FreeBSD ports solution which is called Dports.
In Dports we have :

andromeda# pkg search ganglia

Also you mention a workaround was introduced in DragonFly but I am unable to find it, can you point it to me?
