I think that if you need a single GPL file to compile a LGPL library, the whole must be released under the GPL (and cannot be released under the LGPL), am I right?

That is correct. Well, the LGPL portions remain LGPL, but the
aggregate must be treated as if it were GPL.

I believe the licensing is as intended. I don't know whether they'd be
willing to change the jst portions. The C version is LGPL. Thomas?
