One of the packages in your world requires dev-libs/libgcrypt which
was built with the "static-libs" USE flag. So, the line above is
telling you to add "static-libs" to your USE flag for that package.

These are the items that require libgcrypt with static-libs USE flag
set. Sometimes changing USE flags on thse packages will change the
dependency requirements. Sometimes it's just something new that the
maintainer added since a previous version.

If you don't already have one, you can set package-specific USE flags
in /etc/portage/package.use and in this case you'd add a line:
dev-libs/libgcrypt static-libs
