Thanks Aaron,

Did you re-build Gnuastro from source after installing libgit2 with apt?

It would indeed be good to be creative, and such feedback is indeed very 
valuable. The Conda suggestion was just to avoid such issues causing 
delays in your main work and since you mentioned some dependencies from 
Conda ;-).

Personally, I always build Gnuastro and its mandatory dependencies from 
source myself and don't rely on any package manager (as described in 
[1]): there are so many configure-time options that they can benefit 
from. For example simply adding CFLAGS="-g0 -O3" to the configure script 
will speed them up due to increased compiler optimization features (that 
are usually not enabled by package managers), or things like CFITSIO 
that need a configure-time option to access a FITS file in parallel and 
has CPU-specific optimizations (see [2]).

Cheers,
Mohammad
