Você precisa dos arquivos de desenvolvimento. Eu aposto que eles são chamados de zeromq-devel ou algo desse tipo em distribuições baseadas em RPM.
Eu corri abaixo do comando shell, conforme o site do ZeroMQ, para instalar o PHP-ZMQ:
sudo pear channel-discover pear.zero.mq
sudo pecl install pear.zero.mq/zmq-beta
Abaixo estão os vestígios da instalação:

Já tenho libzmq instalado via Yum no meu servidor CentOS 5 .
Eu também posso confirmar executando abaixo
yum install zeromq
e traços abaixo:
Loaded plugins: fastestmirror

* base: mirror.site.net.au

Setting up Install Process
Package zeromq-3.2.2-13.1.x86_64 already installed and latest version
Package zeromq-3.2.2-13.1.i386 already installed and latest version
Nothing to do
Então eu tenho libzmq instalado, então não vejo porque PHP-ZMQ está jogando erro na instalação.
Qual seria a causa disso?
Instalar o CZMQ via brew resolveu isso para mim.
