the problem is caused by the included Makefile.in
--snip--
ifeq ($(QUIET_COMPILE),1)
  # say a one-line description of the action, do not echo the command
  Q=@echo
  E=@
else
  # do not say the short Q lines, but do echo the entire command
  Q=@echo >/dev/null
  E=
endif
--snip--

here Q is defined and this causes the error, there was a change in the kernel
Makefile between 2.6.24 and 2.6.25 so that all pvfs ebuilds fail at this point.
setting Q=@ instead of Q=@echo >/dev/null fixes this error and all builds fine.

Reproducible: Always

Steps to Reproduce:
1. emerge gentoo-sources-2.6.25
2. emerge pvfs2
3. kernel module won't build

Actual Results:  
kernel module isn't build

Expected Results:  
kernel module should be build

Fixed in cvs, should hit the mirrors in an hour or so.  Thanks for the detailed
report and fix!
