There seem to be multiple problems here.
One issue is that libgsl23 broke its ABI in 2.5+dfsg-1. I've filed #902281
about that.
Another is that the code in xs/ should really be rebuilt from the
sources in swig/, but this is currently skipped; Build.PL has
my $ver2func = do(catfile(qw/inc ver2func/));
which breaks silently now that cwd is not on @INC anymore.
I was able to cobble a working rebuild together with something like this:
perl -I. Build.PL
perl Build clean # removes xs/*
perl -I. Build.PL
perl Build # regenerates xs/*
perl Build test
and the attached two patches. The latter one may not turn out to be
necessary if the deprecated functions get reinstated with #902281.

Subject: [PATCH 1/2] Fix a swig syntax error in Integration.i
This fixes
swig/IEEEUtils.i:11: Warning 453: Can't apply (char const *format). No typemaps are defined.
Creating xs/Integration_wrap.1.15.c
/usr/include/gsl/gsl_integration.h:363: Error: Syntax error - possibly a missing semicolon.
error : No such file or directory while building ( -I/usr/include ) xs/Integration_wrap.1.15.c in pm/Math/GSL from 'swig/Integration.i' at inc/GSLBuilder.pm line 244.
and is needed at least on libgsl 2.4 / 2.5 and SWIG 3.0.12.
