PECL::gnupg cannot be installed in OpenBSD 5.5 - php

Question

I'm using OpenBSD 5.5(with vagrant box:tmatilai/openbsd-5.5).
I installed php, pear and gnupg with pkg_add command.
Also, I installed PECL::APC with pecl command.
However, when I try to install PECL::gnupg with pecl command(pecl install gnupg), install fails with following message.
# pecl install gnupg

Does anyone know how to install PECL::gnupg in OpenBSD 5.5?

Answer 1

In config.m4, remove "-ldl". It's not needed on FreeBSD and I suspect it's the same on OpenBSD.
Also, I had to use the following command line on FreeBSD:
./configure --with-gnupg=/usr/local LDFLAGS="-L/usr/local/lib"
Someone using OpenBSD used the following
./configure CFLAGS="-I/usr/local/include" LDFLAGS="-L/usr/local/lib"
