/opt/local/lib/pkgconfig/pixman-1.pc

it points to the place where the mapcache.xml file is stored. It can
be anywhere accessible by the user that is launching the apache
server. It does not correspond to where the tiles are stored, as
that's configured in mapcache.xml. (the directory where tiles a re
stored should be readable/writable by the user *running* apache (c.f.
httpd.conf)

you have to give the url to the *wms* service, not the tile one, i.e.
http://<server>/cgi-bin/mapcgi?map=foo.map
