 actually, yes :

 Running {{{port install}}} again is successful but I would not take it as
 an acceptable solution, it is more of a proof that parallel build is
 broken in the destroot phase of the Makefile/Portfile.

 I successfully disabled the parallel build in the destroot phase and it
 works fine, so local fix is possible.

 However I believe there is a possible problem resolution at a larger scale
 : is there a rationale for using multiple make jobs for the destroot and
 install phases ? These are not improved at all by CPU parallelism, and I
 guess this is the case for every phase except build. I think of parallel
 destroot/install as a factor of unstability for each and every port which
 has enabled parallel build, did not disable it for the destroot phase and
 uses {{{make}}} as {{{build.cmd}}}, which is the default.
