I added this already in 2008 but Glynn commented like this:

The error could also be caused by a mismatch between PATH and
LD_LIBRARY_PATH (or ld.so.cache, etc) if you have more than one
version of GRASS installed.Or it could be caused by a module linking against GDAL, where GDAL was
built against an old version of GRASS. In that case, it's true that
recompilation is needed, but it would be GDAL that needs
recompilation.In general, error messages should only report what is known; they
shouldn't attempt to guess as the underlying cause.E.g. if write() fails, then you know that write() failed. You don't
know that it was due to insufficient disk space unless errno is set to
ENOSPC. write() can also fail with EDQUOT (quota exceeded), EFBIG
(maximum size of a single file exceeded), EIO (low-level I/O error,
e.g. media fault, failed NFS server), and others.--

Still I tend to actually have the message improved since the
minimalistic notification regularly confuses people.
