Hi Atri:

The first thing I noticed about the above result is there is no
complaint about missing example 00. So something appears to be wrong
with the conditions you used for this test.  My best guess
is you probably had a dirty build tree with some stale 5.9.9 results
mixed in with the trunk version results.

So could you please repeat this test starting from a fresh svn
checkout to an initially empty source tree, and then build starting
from an empty build tree?  That fresh checkout should capture my
recent build system changes so (with luck) there should be no need for
you to patch anything to get the build to work.

Once the unpatched build from trunk works for you, then please test
for run-time issues as above with the test_diff_psc target. If you
still get example 21 run-time issues as above, please try replacing
the % (just for that particular trunk example) with math.fmod.

The example 21 issue (if it still exists for a fresh start) may not be
with % (since that works perfectly for 5.1).  Instead, some other
trunk issue could be the cause of the problem, but replacing % with
math.fmod in the trunk example 21 should should help to answer that
question.

By the way, I ignored your 5.9.9 results since trunk has a number of
changes since 5.9.9, and any of those changes (or your stale build or
whatever it was that made the missing examples/lua/x00.lua go
unnoticed) could be the cause of the example 21 issue.  Also, getting
trunk working correctly is very important to the PLplot developers
since that version will become our next released version (whenever
that release occurs).
