fontconfig : .so.2 not provided by 2.11.1?

I am trying to run xelatex from texlive installation on NetBSD 7.0 amd64.

It complains about fontconfig.2 not found.
In ldd output:

        -lfontconfig.2 => not found

In work/fontconfig-2.11.1/src/.libs/libfontconfig.la I see:

library_names='libfontconfig.so.1.8.0 libfontconfig.so.1 libfontconfig.so'

In Makefile I see

DISTNAME=       fontconfig-2.11.1


Isn't there supposed to be a correlation between package version and the
library version - i.e. shouldn't package version 2.x imply .so.2?
