Build fails in alpine with automake 1.16.2

Hi, maintainers.

I'm trying to compile xaringan in alpine, but this dependency keeps failing. This also happens if I install httpuv directly. It says:

OE> configure.ac:21: error: version mismatch.  This is Automake 1.16.2,
OE> configure.ac:21: but the definition used by this AM_INIT_AUTOMAKE
OE> configure.ac:21: comes from Automake 1.16.1.  You should recreate
OE> configure.ac:21: aclocal.m4 with aclocal and run automake again.
OE> WARNING: 'automake-1.16' is probably too old.
OE>          You should only need it if you modified 'Makefile.am' or
OE>          'configure.ac' or m4 files included by 'configure.ac'.
OE>          The 'automake' program is part of the GNU Automake package:
OE>          <https://www.gnu.org/software/automake>
OE>          It also requires GNU Autoconf, GNU m4 and Perl in order to run:
OE>          <https://www.gnu.org/software/autoconf>
OE>          <https://www.gnu.org/software/m4/>
OE>          <https://www.perl.org/>

Should this file be updated? How? I think this is generated, but I'm not familiar with autoconf/automake. https://github.com/rstudio/httpuv/blob/master/src/libuv/aclocal.m4

Thanks.
