hypermail port problem

[jerome schatten]

*S*ystem: MacMini -- late 2014 - Yosemite 10.10.1; Xcode installed.

I've installed macports 2.3.3 with no problems; I've installed port 
hypermail with no 'apparent' problem. I've followed the MacPorts Guide 
every step of the way.

My first question is this: The install of the hypermail port gives:

jeromes-Mac-mini:bin jeromeschatten$ sudo port install hypermail

Warning: The Xcode Command Line Tools don't appear to be installed; most 
ports will likely fail to build.
Warning: Install them by running `xcode-select --install'.

But Xcode IS installed and the tools work as I've used them elsewhere. 
Is this a or is this not a problem?

If it's not a problem, then at this point, I should be able to launch 
the hypermail binary with a './hypermail' and it should run. But it 
doesn't. The cursor simply moves to the next line and it sits there. No 
error messages, nothing.

I looked at the hypermail and xcode process with top and it reports:
PID   COMMAND      %CPU      TIME     #TH  #WQ  #PORT MEM    PURG CMPR PGRP
[...]
1435  hypermail           0.0       00:00.00    1    0    15 604K   
0B     0B   1435

1404  Xcode                0.0       00:02.26    8    1    249 66M    
72K   0B   1404

So, it doesn't look like hypermail is doing much and Xcode is indeed there.

I'd appreciate any suggestions you might have.
Thanks,
