3.8.0-rc1 parallel build

[c.]

Hi,

If I start a new build of 3.8.0-rc1 with 

 $ configure 
 $ make -j4

The build fails with the following errors:

 Making all in cruft
 mkdir: amos: File exists
 mkdir: blas-xtra: File exists
 mkdir: daspk: File exists
 mkdir: dasrt: File exists
 mkdir: lapack-xtra: File exists
 /opt/local/bin/sed -e "" < 
../../../octave/liboctave/cruft/slatec-fn/derfc.in.f > slatec-fn/derfc.f-t
 /bin/sh: slatec-fn/derfc.f-t: No such file or directory
 make[4]: *** [slatec-fn/derfc.f] Error 1
 make[4]: *** Waiting for unfinished jobs....
 mkdir: slatec-fn: File exists
 make[3]: *** [all-recursive] Error 1
 make[2]: *** [all] Error 2
 make[1]: *** [all-recursive] Error 1
 make: *** [all] Error 2

If I type again 

 $ make -j4

the build completes successfully, I haven't tried a serial build but
I guess this might just be due to some sort of race condition in the
parallel build process.

Has anyone seen anything similar?
