Hi Markus,

Thanks for confirming why my initial fumbling didn't appear
successful :-)

Note that my final outcome was a fresh setup so the hurdles I had along
the way aren't residing in my current GRASS now.

couple of other notes in context below:

good to know what happened :-) (note for later explanations)

I used checkinstall in preference to make install because (at least on
ubuntu) it makes a .deb package for easy uninstall later on (I've found
that handy for spring-cleaning). Also use sudo. My problem here would
have been a result of not doing it in a clean/empty directory as you
noted above.

Use of checkinstall came straight from
(this page has been quite useful for several occasions of me installing
GRASS, thanks!)

The downloads page
would be the starting point - either on this page or on the pages that
can be opened from here that relate to svn e.g.

on this page
you could provide a link 'how to (start to) use GRASS svn' to
(or would both these pages be better condensed into one?)

The same link/s could be done for

Note that 'Working with SVN' page could do with some correction at the
end of the 'first time' section - it goes as far as explaining 'svn
update' but doesn't state one must continue with ./configure, make and
make install (the reader can infer this from the next bit of info on
updating, but it doesn't need to be left up to inference;-) )

Markus, your tips above could be added to that 'Working with SVN' page,
in the "Setting it up first time" section, particularly if the 'svn
checkout' is an alternative to downloading, unpacking and updating a
snapshot as is currently described.
It would also help to give a short explanation on why 'svn checkout' or
'wget - tar - svn update' can both achieve the same outcome (if in fact
they do?) or, simply remove the latter steps and put the 'checkout'
instructions there.

Possibly a condensed note in the INSTALL file from line 39 (or from line
source code or svn/snapshots should be downloaded and uncompressed to
clean/empty directories prior to compilation. Do not try to upgrade
existing versions or move an (official) release to svn by unpacking in
an existing GRASS directory. For more info see website (the 'Working
with svn' page I suggested above could replace the current address, or
leave as is if the extra links I suggested get added).

Hope my comments are of some use! Thanks again for the tips and patience
