Hello,

Just installed TeXmacs-1.99.2 on a Linux computer (where it was not installed earlier), and during the first run got

grozin@dns ~ $ texmacs

TeXmacs] std-warning, Couldn't concretize {}

TeXmacs] missing 'mathsymbols' master
TeXmacs] warning, missing font, loading global substitution list
TeXmacs] missing 'mathsymbols' master
<this last line is repeated many times>

In the TeXmacs window I pressed
$ x - y
and got
x <minus> y
where <minus> is red. Looks like a missing font. What font[s] should I install (and where) to get x-y?
