We are about to release a special external library for this purpose. As a matter of fact you can download the development version of it using cvs. (cvs co libxdrfile). trr support is not functional yet, but xtc works.
Thank you for suggestion! It would be great if the library would be free from such nasty problems.
Could you please post a full cvs command to get the dev version?
