I did notice you talking about 1.6 in your earlier messages, but assumed
it was a typo and you meant 1.16, oops.

My original problem was that I wanted to add an interpolation type to GSL.
Specifically I want monotonic cubic-splines following the description in
Steffen (1990): http://adsabs.harvard.edu/full/1990A%26A...239..443S
I took a quick look at your code earlier and it looks pretty nice. I
noticed you commented out the _integ function - is this something you
could add to make it feature complete with the other interpolation types?
It is important to add automated tests for this. Can you look at
interpolation/test.c and design similar tests for your new method? Also
I think it would be nice to add a figure to the manual illustrating the
differences between cubic, akima, and your new steffen method (similar
to the figures in the Steffen paper). This would help users a lot when
trying to decide what method to use. Do you happen to have a dataset
which shows a nice contrast like Figs 1, 3 and 8 from that paper?
When everything is ready I would be happy to add it to GSL, as we are
already planning to update the interpolation module for the next
release. When I find some time I want to import the 2D interpolation
extension discussed previously, and also add Hermite interpolation.
It would be easiest for us if you could clone the GSL git repository and
make your changes there. You could make a new branch called 'steffen' or
something and publish it to github, or just send a patch file to me,
whichever is easiest.

Dave is correct, I am using an "i686" 64-bit x86 mac. For some reason
it is still looking for the PPC mac header file. The ./configure
stage correctly identifies my system, so it's a bit strange. Also GSL
installs without errors when I do it from MacPorts, and MacPorts
doesn't seem to do anything other than ./configure && make, from my
reading of the portfile.
When I get back to my Mac, I will look at the NOTES file to see if
anything needs to be done for 10.9.
