[gentoo-user] app-misc/screen-4.6.2 fails

Hi,

while updateing app-misc/screen-4.6.2
I got this:

config.status: creating doc/Makefile
config.status: creating config.h
config.status: executing default commands

Now please check the pathnames in the Makefile and in the user
configuration section in config.h.
Then type 'make' to make screen. Good luck.

It looks like a certain texinfo file of this version has a problem.
I am no texinfo expert at all but looking at that file I dont see any
problem.

Does anyone else the problem?
What may trigger it?

My texinfon installation:

[I] sys-apps/texinfo
