Created attachment 222275 [details] Patch to fix the issue. Our ports framework supports "off-side" dependencies, when the port we depend on is outside /usr/ports. That logic however is not followed when dealing with @foo at the end of the reference, causing warnings to be issued. Consider the following dependency line: RUN_DEPENDS= ${PYTHON_PKGNAMEPREFIX}dal>0:/sobomax/myports/devel/py-dal@${PY_FLAVOR} The make package, make clean and some other targets would issue the following warning: [ssp-root@sipit_rack ~/builder/SSP/py-sippyapi.base]$ make clean py27-sippyapi.base-202012161500_4: "/sobomax/myports/devel/py-dal@py27" non-existent -- dependency list incomplete ===> Cleaning for py27-sippyapi.base-202012161500_4 py36-sippyapi.base-202012161500_4: "/sobomax/myports/devel/py-dal@py36" non-existent -- dependency list incomplete ===> Cleaning for py36-sippyapi.base-202012161500_4 I believe this is a recent regression, after rev.510950 (overlays support) by @bapt. https://svnweb.freebsd.org/ports/head/Mk/Scripts/depends-list.sh?r1=471988&r2=510950
