   Hi.

   What if I recompiled my kernel, changing some kernel config options
in the process, but failed to run `psupdate'?

    I am faced with a strange and (to me) worrisome situation in which
I can do the debian.rules build of librl-2.0.3-2 if and only if I
insert a call to `strace' at one pont in the file readline/Makefile,
such that the sole difference between the altered Makefile and the
original is as follows:

--------------------------- quote ----------------------------------
173c173
< 	$(DLL_TOOLS_PATH)/mkimage -f -l librl -v $(DLL_VERSION) -a $(DLL_LOADADDR) \
---
> 	strace $(DLL_TOOLS_PATH)/mkimage -f -l librl -v $(DLL_VERSION) -a $(DLL_LOADADDR) \
---------------------------- unquote -------------------------------

   Any possibility of a connection between this fact and the fact that
up until a few minutes ago I had indeed been using a kernel that I had
recompiled without updating the file `/boot/psdatabase'?
