Comment (by repagh):

 Huh?

 I am getting the same error if I remove the splinter-3.0.zip that I had in
 my files section.

 That splinter-3.0.zip was downloaded through the github web interface. I
 used it to check how to build splinter and develop the portfile. It is a
 real zip file, and has rmd160=d2dce503fbb8c89b4a17a912ce689e98dcdddefe

 The splinter-3.0.zip that macports downloads is *not* a zip file. It has
 rmd160=4371f8e8617081b2e71d3a14181b522293b97493. The file cannot be
 unpacked through unzip, and is actually a tar.gz file, I successfully
 unpacked it by running it through gzip and tar. Its top directory is
 bgrimstad-splinter-2c877c0 and the contents are identical to those of the
 real zip file.

 This is really confusing me now. Am I doing something wrong in the
 portfile? Does this happen only on the splinter project, or is it
 something common? I had expected to get the zip file through the github
 portgroup, but am getting a tar.gz, and with the wrong main dir to boot.

 Or does the github portgroup only download tarballs, and do I only get the
 wrong extension with the use_zip option? That looks to me like a bug.
