Those the directories which are referenced in the binary,  I know the generic upstream perl source process has always created them,  but they're not included in the current cygwin package.   As a total guess, empty directories are maybe now being elided in the cygwin packaging process?

not on usr/local

Sorry, I should have be more clear.

We can discuss if the perl package should deliver empty directories like

     usr/share/perl5/site_perl/

and similar. It seems reasonable but I am not a Perl expert, however
a distribution package should never write on "/usr/local"

https://tldp.org/LDP/Linux-Filesystem-Hierarchy/html/usr.html

" The /usr/local hierarchy is for use by the system administrator when 
installing software locally. It needs to be safe from being overwritten 
when the system software is updated"

Marco
