I want to add a couple of comments for others and for my own future reference.

Here: <path to your .pem file> you don't need the < and >, just the path/to/your/pemfile.pem

Here: <configfile>XXXXXXXX</configfile> you don't need to replace the XXX's for this test.

Here: <keyfile>/home/XXXXX/etc/linkpoint/XXXXXX.pem</keyfile > you DO need to replace the XXX's with your path and filename.

I continued to get this error after moving a site to a new server: curl: (58) unable to use client certificate (no key found or wrong pass phrase?)

It turned out the pem file had changed somehow during the transfer, and getting the pem again from First Data and pasting directly into the file in the command line editor fixed the problem.
