What I have done in the past is create "slave" ports. Say the port you want to 
install twice is in ports/category/foo. Make a new directory 
ports/category/bar. Inside that directory, create a Makefile similar to this:

PORTNAME=		foo
PKGNAMESUFFIX=	_bar-duplicate
COMMENT=		This is the foo port but it installs as foo_bar-duplicate
PREFIX=		/path/to/alternate/prefix
# ...you may want other options here ...

MASTERDIR=		${.CURDIR}/../foo

.include "${MASTERDIR}/Makefile"


Install once from category/foo and once from your new port's directory and 
away you go. Again, the porter's handbook has lots of useful information 
about everything above.
