Shouldn't happen unless you accept our versions. dpkg should ask you
if you want to keep your changes or install the maintainers.

I assume you have
	TEXMFHOME = TEXMFVAR = TEXMFCONFIG = $HOME/.tex
right?

So in short, that is the absolut correct search path due to
	{TEXMFCONFG,TEXMFVAR,TEXMFHOME}/tex/{$progname,generic,}

What is *useful* for you? 
Do you keep TDS structure in ~/.tex/?
Do you have ~/.tex/tex/latex/...?

Why: Becasue (I assume) you defined TEXMFCONFIG=TEXMFVAR=TEXMFHOME. Not
a good idea anyway, but you defined it like that.

Taken care of: No, if you want this then it appears double, but it does not
hurt at all.

You need to understand how searching works. The search path is set to
(more or less with variations):
	$TEXMF/tex/{$progname,generic,}//
and
	TEXMF = {$TEXMFCONFIG,$TEXMFVAR,$TEXMFHOME,$TEXMFSYSCONFIG,!!$TEXMFSYSVAR,!!$TEXMFDEBIAN,!!$TEXMFMAIN,!!$TEXMFLOCAL,!!$TEXMFDIST}


That is where the stuff comes from.


=============

YOu said "too late" ... what doe sit mean? Are the files not found???
WIth the settinggs you have the files should be found without any
problem ...

Best wishes
