This is normal. 'gperf' is generally not among the tools that a user needs when configuring from a distributed tarball. It is the responsibility of whoever creates that tarball (e.g. via "make dist") to run gperf on the appropriate input files and to include the generated files in the tarball. The Makefile.am rules included in the gnulib modules ensure this, if automake's "make dist" target is used to create the tarball. Bruno
