X support for the amd64 port was added just a few days ago and nobody 
has put the effort yet to make it work well.
From my very limited testing, xdm and twm seem to work, while e16 crashes.
What can you do? You can compile everything with debugging information 
and obtain core files of the crashing apps. Then you can (try to) 
analyse the core files with gdb.
To compile the base system with full debugging information you put the 
following in /etc/make.conf:
   CFLAGS+=-g
   STRIP=
To build pkgsrc packages with full debugging information you put the 
following into /usr/pkg/etc/mk.conf:
   CFLAGS+=-g
   INSTALL_UNSTRIPPED=yes
You can also use ktrace in your debugging.
