Bugzilla Bug 169973

After upgrading app-crypt/opencdk from 0.5.5 to 0.5.7, gnutls-extra.so.13 fails
to open libopencdk.so.8:

Normally, this is resolvable by revdep-rebuild, but in this case,
revdep-rebuild reports nothing amiss, since /usr/lib/libopencdk.so.8 does
exist.


Reproducible: Always

Steps to Reproduce:
1. emerge --oneshot =app-crypt/opencdk-0.5.5
2. emerge --oneshot =net-libs/gnutls-1.4.4-r1
3. emerge --oneshot =app-crypt/opencdk-0.5.7
4. srptool -v

Actual Results:  
# srptool -v
srptool: /usr/lib/libopencdk.so.8: no version information available (required
by /usr/lib/libgnutls-extra.so.13)
GNU TLS srptool, version 1.4.4. Libgnutls 1.4.4.

(Similar for psktool, gnutls-cli, gnutls-cli-debug and gnutls-serv)


Workaround:  re-emerge gnutls after upgrading opencdk.  This is not an obvious
workaround, since revdep-rebuild doesn't report any problems.

Could the library version in opencdk be bumped, or could a warning be printed
on emerge that gnutls has to be rebuilt?

That's what revdep-rebuild is for...

Jakub, please read the ticket before giving glib answers like this.  In
particular, this part - the second sentence in the ticket:

"Normally, this is resolvable by revdep-rebuild, but in this case,
revdep-rebuild reports nothing amiss, since /usr/lib/libopencdk.so.8 does
exist."

Yeah, I sure would if only bugzilla dropped its goddamn habit of jumping on
next open bug; a.k.a. comment #1 didn't belong to this bug at all.

As far as I see the "no version information available" does not make the
product not to work.

tools-portage: Can revdep-rebuild detect such issues and rebuild the affected
packages?

Works for me!
