Bug#1003964: pandoc doesn't start: error while loading shared libraries: libcmark-gfm.so.0.29.0.gfm.0

[John MacFarlane]

A note from upstream, in case it's helpful:  we haven't depended
on cmark-gfm since pandoc 2.10.1 (released a year and a half
ago).  If you could move to a more recent version of pandoc, this
would avoid the problem entirely.  I'm aware that issues of
policy and packaging may make this difficult, though.
