apart from bug fixes (and/or if someone submits more drawing definitions)

in fact, as we move on to luatex, the context version for pdftex / xetex
is frozen as well

if we kno wwhere the problem sits it will of course be solved, however
as i don't run latex i cannot see what goes wrong

in context mkii metapost support has been integrated for quite some time
and in context mkiv it can be processed without noticing so there
ppchtex uses even more metapost (which is why there are also some extras)

contextgarden.net) which will give you an independent tree that does not
interfere with anything else

btw, an easy test is:

\starttext

\startTEXpage

... some chemical ...

\stopTEXpage

\stoptext

which will give you a graphic that you then can include in a latex doc
