Customisation of the MacPorts download method

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?

Can you elaborate on the issues?
Rather than avoiding the problem it’d be best to fix it.
