curl/clamav on 3.7-stable breaks

[Uwe Dippel <udippel_(_at_)_uniten_(_dot_)_edu_(_dot_)_my>]

curl has been updated for stable recently. So I issued a make / pkg-delete
curl [where I also had to delete the dependent clamav] / make install.
Everything went smoothly until  
pkg_add /usr/ports/packages/i386/all/clamav-0.87.tgz
which bounced with

Can't install /usr/ports/packages/i386/all/clamav-0.87.tgz: lib not found curl.2.2
Even by looking in the dependency tree:
        arc-5.21e, unzip-5.51, unarj-2.43, curl-7.15.0, gmp-4.1.4, zoo-2.10.1, unrar-3.43, bzip2-1.0.2, lha-1.14i.p0
Maybe it's in a dependent package, but not tagged with @lib ?
(check with pkg_info -K -L)
If you are still running 3.6 packages, update them.

What went wrong ?
