Mikael,

I don't know what dpkg does, but I would guess it is somehow not honouring
your environment.  lt_platforms.h checks for gcc 2 and 3, so I would assume
things are still picking up gcc 4 for some reason.

You might trying setting CXX instead of (or in addition to) CC since this
is a c++ project.

I trust any package you build would only be for internal use, right?  There
are non-trivial requirements to redistribute Lizardtech libraries (even if
you are putting it in non-free).

Best regards,
