Hm, you're right. I thought it was the latest beta release, but that's
2.48. Anyway, no need to worry about it here.

Build gets farther now, but fails later on complaining about caml__frame:

cd gsl && ocamlc.opt -ccopt "-I/usr/include -I/usr/include/ncurses -ggdb
-O2 -pipe -Wimplicit-function-d
-DHAVE_INLINE -DHAVE_FENV -g -O2" -c mlgsl_matrix_double.c
ml_curses.c:1:0: warning: -fPIC ignored for target (all code is position
 #include <caml/mlvalues.h>
In file included from mlgsl_error.c:9:0:
mlgsl_error.c: In function ‘ml_gsl_raise_exn’:
/usr/lib/ocaml/caml/memory.h:236:12: error: ‘caml__frame’ undeclared (first
use in this function)
     (void) caml__frame, \
/usr/lib/ocaml/caml/memory.h:309:3: note: in expansion of macro
   CAMLxparam2 (x, y)

This isn't actually a problem now, I was only using orpie as a test. Orpie
hasn't been updated in several years, and the source site has gone dark. So
I may never actually need to build it again. If I do, then I'll have to
solve this.

Thanks for maintaining all the ocaml packages. I see BTW that you added
ocaml-lablgtk2. Some time I'll get back to trying to package Unison with
the GTK2 GUI.
