openmpi doesn't install under F10

[Dennis Glatting]

OpenMPI fails to install under FreeBSD-10 BETA4. It previously installed 
under BETA3. The key difference appears to be version _1 vs _2. Data 
follows.

The system:

Coke# uname -a
FreeBSD Coke 10.0-BETA4 FreeBSD 10.0-BETA4 #1 r258932: Wed Dec  4 14:57:28 
PST 2013     root at Coke:/usr/obj/usr/src/sys/XYZZY-FBSD10  amd64

Key part of the Makefile:

PORTNAME=       openmpi
DISTVERSION=    1.7.3
PORTREVISION=   2

The relevant diagnostic output:

Coke# make -dA install
...
+ echo '===>   Registering installation for openmpi-1.7.3_2'
