"Unpack lyx-1.4.x.tar.bz2 in /usr/local/src
(replace x ^ to match your archive name)"
I was reading over Enrico's detailed instructions.
I can't find a lyx 1.4.0.tar.bz2 or tar.gz for download.
The Pre5 doesn't have a configure file to execute
the several ./configure switches in Enrico's Howto.
The Pre3 release had a configure file but that isn't
worthwhile trying to build.
I downloaded the current cvs and didn't find a
configure file. I was wary of mixing Enricos'
Cygwin instructions with the INSTALL notes.
And the cvs option is not offered in the Howto.
The only download folder I found for lyx-1.4.x
was ftp://ftp.devel.lyx.org/pub/lyx/pre/
