building xorg/bin/proxymngr fails w/ readonly src

[Kurt Schreiner <ks%ub.uni-mainz.de@localhost>]

Hi,

on one of my i386 systems build.sh...distribution fails while trying
to build proxymngr (-current source ca. 4 hours "old", destdir and 
obj/external/mit cleaned out):

/u/NetBSD/src is mounted readonly from one of the sun server here:

Is this to be expected?
