On recent CURRENT (FreeBSD 15.0-CURRENT #26 main-n268743-a58813fd701e: Sat Mar  9 07:04:03 CET 2024 amd64), updating and/or upgrading ports via portmaster (portmaster-3.29_2; ports-mgmt/portmaster), some ports seem to have trouble with portmaster, i.e.

devel/libpci

Building the port via make is fine, using recent portmaster fails with:
