Request for advice on packaging of libgoops

[Mikael Djurfeldt <mdj@mdj.nada.kth.se>]

Hi, I'm a new Debian developer.

I'm the maintainer of the GOOPS package (the object system for Guile).

There are currently two Guiles in Debian: version 1.3 and 1.4.

GOOPS will compile differently under libguile1.3-dev and
libguile1.4-dev.

I'm therefore considering breaking up the GOOPS packages into
libgoops1.3-0.9.0 and libgoops1.4-0.9.0, each compiled under a
different Guile.

How do you usually handle version numbering and control files under
such circumstances?  (Is GUILEVERSION-GOOPSVERSION as showed above
OK?)

Should I produce two separate source packages for libgoops1.3 and
libgoops1.4?

Best regards,
