apt: prebuilt package same as src pkg + build?

[M Joonas Pihlaja <jpihlaja@cc.helsinki.fi>]

Hello,


I'm a new Debian user and have a problem with apt-cache and
dselect using the source package CDs:  They don't know about the
source packages!  I can use apt-get to fetch and build the source
once I know the package I want, followed by calling dpkg to
install it.

Since in theory source packages are just one step away from
prebuilt ones[1], I'd like apt to consider them equal.  Except it
would have to build them before installing.

Have I missed an argument to the programs, or something silly
like that?  I'd much appreciate any help.

Regards,

Joonas
