Chris,
The way to do this is to recompile the new lyx under a different name.
Get the sources (lyx-1.1.6pre3.tar.gz), untar them.
There are two configure switches that help you.
One is --with-lyxname, which sets the name for various directories and
files (but not the main executable) to something other than 'lyx'.
The other is --prefix, which sets the location where everything is
installed. You can thus install things in a temporary place, not
/usr/local or /usr.
What I would do is not install the files to /usr/local, but rather do
something like:
configure --with-lyxname=lyx-1.1.6pre3 --prefix=~/tmp/lyx-1.1.6pre3
+any other switches you like to add.
The --with-lyxname option is useful because then the default ~/.lyx
directory name is actually ~/.lyx-1.1.6pre3 (assuming the example above)
and thus your lyxrc will not be overwritten.
You then run the program from ~/tmp/lyx-1.1.6pre3/bin/lyx (set an alias
for that).
Note that you can test the program without 'installing' it. Configure
--with-lyxname (again to preserve ~/.lyx), and compile with just 'make'
(and not 'make install' if you've been using that). Then you can run the
exectuable from [wherever the sources are]/src/lyx
A final word of caution - if you plan on using tabulars, the file format
is being changed right now, so lyx-1.1.6 may not read tabulars written by
lyx-1.1.6pre*. I think all versions can import old-style (1.1) tables.
HTH,
Lior.
