gcl-dwdoc.info not installed with gcl 2.7.1?

I built gcl from sources and everything works as expected. However, when 
I do something like:

```

 >(describe 'quit)

QUIT - external symbol in SYSTEM package
-----------------------------------------------------------------------------
QUIT [Function]
(not found "gcl-dwdoc.info")
-----------------------------------------------------------------------------

```

I looked around in prefix/share/info and find other info files but not 
gcl-dwdoc.info.  It was built though.
