This probably means that MrEd wasn't compiled with GL support.

(I forgot about this potential problem, but now I remember that it was
relevant to the question of where sgl-v205.plt installs itself, at
least under Unix.)

Unfortunately, there's no solution except to re-compile MrEd.

It's a little puzzling that GL support was disabled during "configure".
Under Linux, GL support should be enabled by default, at least when the
relevant headers and libraries are present. Maybe a library is missing?
(The headers must be present, others sgl wouldn't have compiled.)
