I have not checked this with 5.x but...

10.42.0.1:/usr/src on /usr/src (nfs, read-only)
10.42.0.1:/usr/obj on /usr/obj (nfs, read-only)

/usr/src and /usr/obj were precompiled on the other (NFS server) machine
with "make buildworld".


then on this machine: 
"Make installworld" with /usr/src and/usr/obj NFS mounted readonly.

Why is perl trying to write to the obj directory in the 'install" phase?
shouldn't it have finished all that sort of stuff  by then?
