What you are asking for is I am afraid really not possible, I suspect. The 
installation prefix is a fundamental parameter in most port builds. Many 
directly use this via the ${prefix} variable, which is a single valued path. 
What you are asking for is for a port use to use one location for some ports 
and a second one from others. I just don’t see how that could work.

I think your only option is really to go with a second installation using a 
custom prefix.

Chris, thanks for the quick reply.  You are correct, a private macports
installation would enable testing ports without special privilege.
Actually I have already done this many times for testing and debugging
other cases.

However, I would like to find an intermediate solution that avoids full
build-up from sources.  My main reasons are (1) test sensitivity to
installed ports in the system prefix; (2) save time and effort; and (3) be
able to provide compact, uncomplicated reproducers to third parties.

If not currently possible, it would be nice to have a new feature to enable
local repository testing, with fallback to the system prefix for everything
not found in the local repository.

Hi,

I might be wrong, but I do not believe it is possible to temporarily change the 
install prefix, for a single port.

Most probably you will need to start a new installation, using a custom 
installation prefix, from scratch. see

https://www.macports.org/install.php#source 


on installing from source, which you will need to do to change the installation 
prefix, as its a configure time option.

Test in local repository without privileges

[Dave Allured - NOAA Affiliate via macports-users]

I am on a corporate network with ports installed normally in /opt/local,
controlled by system admins.  Users do not have any write access into
system directories.  I would like to use a local portfile repository in
user space, as described in Macports guide 4.6.

How can I test ports in the local repository?  The "portindex" command
works as expected in this directory.  However, "port install" fails with
"Insufficient privileges to write to MacPorts install prefix".  I need a
way to tell "port install" to use a local prefix, rather than the default
system prefix, for only the port under test.

I figured that I could avoid tampering with the protected sources.conf, by
manually pre-staging the desired distfiles in the local repository.  Here
is my embryonic directory structure:

$HOME/portx/science/netcdf-fortran/Portfile
$HOME/portx/science/netcdf-fortran/files/patch-Makefile.in.diff
$HOME/portx/var/macports/distfiles/netcdf-fortran/netcdf-fortran-4.5.2.tar.gz

Thank you for any advice.
