You should upgrade to a recent eric4 release.

It seems, that macPorts uses a different installation scheme than eric 
expects. Due to the fact, that I don't own a Mac (donations welcome ;) ) I 
can't work on this. I hope, a Mac owner can support here. Currently eric 
expects the Qt tools in a path assembled from the one entered in the Qt config 
page appended by "bin/<tool name>.app" or just "/<tool name>.app" if the first 
doesn't exists. That is the scheme used by Mac OS X bundles. The entries for 
prefix/postfix on the Qt config page are used to modify the tool name (e.g. 
Ubuntu uses this to have Qt3 and Qt4 installed in parallel by appending -qt4 
to the tools (e.g. designer-qt4).

The path to the tools should be in the search path (e.g. PATH environment 
variable).

You may ignore these warning. They are just telling, that there is no 
translation available for your locale, which is normal in the case of English 
because that is built-in. To get rid of these you may set the desired language 
on the Interface config page.
