Roberto,

it can be a older version than needed,
ldd and cygcheck will not notice the difference.

It is usually due to a an error in upgrade.
It can happen when you run setup but some cygwin program/process
was still running and the used libraries can not be upgraded.

Check is some /usr/bin/*.new libraries are present.
In that case a re-boot could solve the issue.

In the cygcheck.out you can look at the date of the specific
library and compare with the one in the latest package

https://cygwin.com/cgi-bin2/package-grep.cgi

In case of mismatch, close all process and re-install the package
containing that library.
