From Gentoo Wiki
The app-portage/portage-utils package is a collection of very fast utilities written in C, which are meant to offer a faster but more limited alternative to their app-portage/gentoolkit counterparts. Please note that portage-utils is not meant to replace gentoolkit. Its utilities are much more efficient than the equivalent ones from gentoolkit and might be better suited to be used in scripts that need to call Portage repeatedly, but they do not offer the same functionality. It does not consider eclasses and does not provide tools like revdep-rebuild or glsa-check.
