During compilation, pkg-config is invoked by the podman build on gpgme. If it is missing, building will fail. Per the definition of BDEPEND, while gpgme is not executed during the build, it is required to exist on CBUILD for the build to succeed. Reproducible: Always Steps to Reproduce: 1. emerge --onlydeps app-containers/podman 2. emerge --C app-crypt/gpgme 3. emerge app-containers/podman Actual Results: Build dies with ``` # github.com/proglottis/gpgme # [x86_64-pc-linux-gnu-pkg-config --cflags -- gpgme] Package gpgme was not found in the pkg-config search path. Perhaps you should add the directory containing `gpgme.pc' to the PKG_CONFIG_PATH environment variable Package 'gpgme' not found ``` Expected Results: Build succeeds.

Minor error in reproduction steps, fixed: 1. emerge --onlydeps app-containers/podman 2. emerge -C app-crypt/gpgme 3. emerge --nodeps app-containers/podman
github.com/proglottis/gpgme uses gpgme.h (and probably a related library), so the dependency belongs in DEPEND, not BDEPEND.

app-crypt/gpgme already is in DEPEND, as DEPEND includes RDEPEND, where app-crypt/gpgme is specified. I think that the issue here pops up during cross-compilation only. We don't override PKG_CONFIG environment variable, so cgo will use pkg-config instead of <whatever-triplet>-pkg-config. In flatcar we fixed it with: if tc-is-cross-compiler; then tc-export PKG_CONFIG fi Will file a PR on github.
