With update form version 3 to 4, the perl bindings for ZMQ broke. I had to mask the net-libs/zeromq package. There exists a perl ZMQ4, but this seems quite young and has one open bug report on CPAN and I do not know, if amavisd - which makes use of ZMQ - is compatible with a newer version. I checked the package content of net-libs/zeromq and it seems it only has these libs: /usr/lib64/libzmq.so.3 /usr/lib64/libzmq.so.3.0.0 So I am pretty sure, we could have slots here. Even if I am not a newbie at all, I already saw that the package carries something like 0/3 or 0/4 as SLOT, but I do not understand what it means and it seems not to be a slot, right? Reproducible: Always
Do you think this is still required? There will be a problem due to headers and pkgconfig file.
Yes. Unfortunately. As of writing this bug, I could not use zeromq with amavisd anymore.
Have you really tried using =mail-filter/amavisd-new-2.11.0-r2 against net-libs/zeromq-4.x? I have a non-Gentoo setup where this is working fine... so if this really doesn't work we maybe have to fix something in Gentoo but this should be easier than slotting this package.
