OK,

I am running OS X 10.9 in VirtualBox on a MacMini, itself running 10.9. The 
purpose is to have a build/test image that can be thrown away and recreated. 
MacPorts 2.3.1 is installed on the virtual machine guest from the provided 
package: 
https://distfiles.macports.org/MacPorts/MacPorts-2.3.1-10.9-Mavericks.pkg

When trying to install wcslib with the following command:
  sudo port install wcslib
The command hangs at the point where it is trying to download the file 
wcslib-4.23.tar.bz2 from ftp://ftp.atnf.csiro.au/pub/software/wcslib/. At some 
point it eventually times out and the command fails.

When trying to download the file 
(ftp://ftp.atnf.csiro.au/pub/software/wcslib/wcslib-4.23.tar.bz2) manually with 
the curl command, I reproduce the hang. However, when trying to download the 
same file with wget it downloads successfully.

Looking through the verbose trace of curl's connection produces no clues as to 
what may be wrong:

$ curl -v ftp://ftp.atnf.csiro.au/pub/software/wcslib/wcslib-4.23.tar.bz2

(hangs, no more output)


So, its clear its a networking problem, but its not clear at what level. It 
could be either on the server side, in the VirtualBox networking, or in curl 
itself.
I would love to solve the route cause of the problem, but I do not see how this 
is going to be fixed anytime soon. Thus, for the time being I need a workaround 
if possible: Can one tell MacPorts to use a different download tool?

Kind regards.

Artur

Subject: Re: Customisation of the MacPorts download method

Can you elaborate on the issues?

Rather than avoiding the problem it’d be best to fix it.
