can't build gem: possible bug in the tools you use to build with?

@miyucy ( iirc ), of snappy, cracked something,
so this is copy-pasted from the snappy issue-tracker:

I think you've got it!

$ ruby -v -rrbconfig -e "puts RbConfig::CONFIG['MAKEDIRS']"
ruby 3.0.2p107 (2021-07-07 revision 0db68f0233) [aarch64-linux-gnu]
/usr/bin/mkdir -p

But there IS no mkdir, there!

That needs to get upstream to someone
( meaning you, who actually know what you're doing,
needs to get that to someone : )

$ grep -A 3 -B 3 mkdir $(gem env gemdir)/gems/snappy-0.3.0/ext/Makefile
RM = rm -f
RM_RF = $(RUBY) -run -e rm -- -rf
RMDIRS = rmdir --ignore-fail-on-non-empty -p
MAKEDIRS = /usr/bin/mkdir -p
INSTALL = /usr/bin/install -c
INSTALL_PROG = $(INSTALL) -m 0755
INSTALL_DATA = $(INSTALL) -m 644

again!

I think they found the bug is in Ubuntu's system-wide Ruby,
but that is the opinion of an old fool who's trying to learn basic programming,
so you actual-programmers know better whether this is significant,
& to what degree.

Salut, Namaste, & Kaizen!
