Problem installing PEAR package with GMP extension requirement

Question

I want to install the Crypt_DiffieHellman PEAR package, that gives me the following error:

pear/Crypt_DiffieHellman requires PHP extension "gmp"

So I installed the gmp extension (using MacPorts' "php5-gmp"), both php -m and extension_loaded('gmp') indicate that the extension is loaded. However I still get the PEAR error when I try to install the package.

Am I missing something here? Or is this a (known) bug with the package/PEAR installer?

Answer 1

What solved my problem: use the -f (force) argument to ignore missing dependencies. In my case I was sure the extension was installed, so the installer could do without checking this particular extension.
