Actually, no. I noticed that it had "8bit ascii" characters inside so on 
a hunch I sent it through iconv and got a different error message

Error in read.spss("xxx.por", use.value.labels = FALSE) :
  file 'xxx.por' is not in any supported SPSS format

So read.spss() recognizes the format of the original file alright, it's 
just that something in the file does not match the format that 
read.spss() expects. It reads at least one .por file, namely the one 
that ships with the source for the foreign package in the tests 
directory (pbc.por). It is not unlikely that it can be confused by 
character set encodings and CR/LF inside value labels, though.
