I set that up and except for one strange problem, which I resolved, worked 
seemingly all fine. The strange problem was this: with the old version of Linux 
Libertine (4.4.1) word "Pērse" was output well, but with the new 4.7.5 one it 
was output so that 'ē' gets printed right onto 'P' without counting P's 
width... Here is why for me the old versions of fonts will now matter and I 
set up a git VCS repository on that folder...

Otherwise than that... Given I only intend using XeTeX, what could be missing 
in the above mentioned setup? I mean, something important, that might show up 
just later...

Anyone knows some work, which has to tell about math output differences between 
pdflatex and xelatex? Anyone has some particular math font(s) to advice for 
copying? (math output works for me without that too..)

find -regextype posix-extended -regex ".*(m|M)ath.*\.otf$"

Maybe those?
