This one is only neccessary

because abbrevs.sty is already in TeX Live (I realized that lately while
invesigating the problem).

first, it is not a problem with `abbrevs.sty' but with `abbrevs.cfg', but
if to be more accurate it is problem with class file and `relsize'

To process file without such error you should create simple `abbrevs.cfg' file
in current directory (directory where document is located), like below

<file name="abbrevs.cfg">
%%% Dumb

I checked compilation on my system.

Details: the problem underlies in `abrrevs.cfg'. That file uses `relsize'
package and redefines \DateMarkSize using the `relsize' command. Seems
that machinery used by `relsize' package can't work with font sizing
commands defined by the class.

IMHO, that problem can be reported to class authors but I don't think
they could fix the issue quickly, on the other hand, `relsize' package
could find solution for they code to deal with such cases.
