Okay. Am I wrong in thinking that a newer version of freetype *might* work
around the problem (the real solution, avoiding LD_LIBRARY_PATH, seems to
involve a *lot* of work and is way above my current comprehension of sage
sources) ?
If so, does an adaptation of the sage developper's guide exist for the
gi-supported versions of sage (6.0 and up) ? Creating a new spkg for 5.13
seems a bit futile now, and I checked that I could build sage 6.0.
In other words, where can I find a bit of git handholding for integrating a
"better" freetype in sage ? <Blush> I'm new to git </Blush>.
I agree that another workaround might be to *remove*
freetype-2.3.5-incompatible fonts from "big machine", but there might be
hell to pay with other programs...

That's what I thought, but R's dyn.load might be different (however, trying
to dyn.load R's X11 library with a corrected path gives the same result as
with the original path).
