 Manuel,
 
 I updated pkgsrc to CVS date 2018.09.06.14.10.59 and switched
 WRKOBJDIR from tmpfs to ffs, but the xentools48 build still failed.
 
 I have now tracked down the cause of the problem to a file descriptor
 leak in Perl:
 
   https://rt.perl.org/Public/Bug/Display.html?id=133314
 
 which is invoked from stubdom/Makefile:
 
        find $@ -type f | xargs perl -i.bak \
                 -pe 's/\b_(tzname|daylight|timezone)\b/$$1/g'
 
 A possible fix would be to add perl commit
 3d5e9c119db6b727684fe75dfcfe5831c4351bec as a pkgsrc patch.
 Alternatively, we could work around the issue by changing
 "xargs" to "xargs -n 100" in the above Makefile fragment.
 
 I bet the reason you were unable to reproduce the problem is either
 that you are not running the most recent pkgsrc perl, or that you
 have increased the limit on the number of open file descriptors from
 the default.
