we can also package up SOFA, making weekly packages just like casacore-data (measures data)

A weekly release is definitely not necessary, SOFA has a decent release system (though not a very modern packaging system). It could be packaged whenever SOFA has a release.

However, since installing sofa from source it pretty straightforward, see the jenkins script, I don't think we need to package it.

many packages are quite straightforward to install from source, that doesn't mean you want to do it all the time :)

is there only a build time or also a runtime dependency on SOFA?

There is only a test time dependency on SOFA (and when running the test, it's probably run time).

[gijzelaerr]

ah yes, i mean test time

Removing SOFA seems to be good for debian packaging as well, since the SOFA license may not be compatible enough with debian's license:

As you might have seen from the message, the inclusion of SOFA was the reason why the package was rejected by the Debian ftp-masters.

In Debian, SOFA is already packaged, but in non-free. However, there is a free replacement available: erfa. Erfa is based on SOFA (and synchronized regularly) and differs only in the license, and in the function prefixes (era instead of iau). Erfa is also packaged for Debian and Ubuntu.
So, iof you feel it is really worth to keep these checks, it may be worth to consider switching to erfa.

Let's see if the pull request is accepted. If it is, we don't need to switch to erfa.
