V8 on Centos 7 is wrong?

[gaborcsardi]

❯ writeLines(remotes::system_requirements("centos", "7", package = "V8"))
yum install -y epel-release
yum install -y libcurl-devel
yum install -y openssl-devel
yum install -y v8-devel

But on CentOS 7:

[root@c5a7e984e6d8 pkgdepends]# yum install -y epel-release
Loaded plugins: fastestmirror, ovl
Loading mirror speeds from cached hostfile
 * base: mirrors.xtom.de
 * epel: mirrors.ptisp.pt
 * extras: mirrors.xtom.de
 * updates: centos-altarch.mirror.liteserver.nl
Package matching epel-release-7-12.noarch already installed. Checking for update.
Nothing to do
[root@c5a7e984e6d8 pkgdepends]# yum install v8-devel

No package v8-devel available.
Error: Nothing to do

OTOH, V8 compilation fails on CentOS 7, anyway:

* installing *source* package 'V8' ...
** package 'V8' successfully unpacked and MD5 sums checked
** using staged installation

Actually, this is not an issue on x86_64, where EPEL does have a v8-devel package. Only aarch64 is problematic, which is OK, I guess.
