Comment(by mathew.eis@…):

 I can confirm seeing the same issue. We see it regardless of whether the
 underlying nfs filesystem is xfs or ext3.

 The culprit appears to be in 'proc fileAttrsAsRoot {file attributes} {' in
 share/macports/Tcl/port1.0/portutil.tcl

 Specifically, the line 'eval file attributes {$file} $attributes' is
 trying to run (among other things), the following TCL command, which
 fails:

 file attributes /path/to/foo -readonly 0

 Arguments about whether running MacPorts on a network aside, would it be
 possible to subvert this command? It seems to me unnecessary to forcibly
 state that a file should NOT be read-only.
