The error comes from the fact that the  find  command  (the  part  in
`...`  above)  generates a long list of file names which exceeds some
buffer in your shell.

I try. Find the statement in the Makefile and use xargs  to  avoid  a
long argument list. Something like this might help:

--- Makefile.ORIG	2006-01-03 15:15:48.000000000 +0100
+++ Makefile	2006-01-03 15:16:55.000000000 +0100
