Mikkel,

You should look at pdfmark.pdf, which you should find in somewhere like:-

/usr/share/doc/groff-1.22.3/pdf/pdfmark.pdf

This describes how to embed pdf links. It also documents using the macro -
mspdf which combines -ms and -mpdfmark, which is probably what you want. The 
macros and documentation are by Keith Marshall. Also, have a look at the 
program pdfroff, which can be used for producing the final pdf file using 
groff postscript and ghostscript.  You can also use these macros with the -T 
pdf device, but if have forward references you need to run it twice in a 
pipeline such as:-

groff -Tpdf -dPDF.EXPORT=1 -dLABEL.REFS=1 -ms -z  file.trf 2>&1 | LC_ALL=C 
grep '^\\. *ds' | groff -Tpdf -ms - file.trf

Cheers
