For installing pkgsrc on Solaris/sparc, I mount the source tree from my Solaris/i86-machine via NFS. Installing lang/perl5 now fails with

I am using this setup for the last two years and never had a problem like this so far, neither with lang/perl5 nor any other package. lsof showed no processes accessing the .nfs files, neither on the NFS server nor the client.

I have tried compiling with every combination of MAKE_JOBS=1 (default in mk.conf is 4) and USE_CWRAPPERS=no (default is "yes" since yesterday), but always get the same result.

So far, lang/perl5 seems to be the only package affected, but I have built only about 30 other packages since the last bootstrap.
