Disabling the `caps` USE flag allows it to link.
USE_CAP=$(usex caps) is probably an invalid way to link to libcap. Can you post your emerge --info for completeness?
The build system failed to extract libcpa's flags: make -j4 -l5 USE_CAP=yes USE_DEBUG=no USE_PYTHON=no USE_SECCOMP=yes Name field occurs twice in '/usr/lib64/pkgconfig/libcap.pc' Name field occurs twice in '/usr/lib64/pkgconfig/libcap.pc' Can you post your contents of '/usr/lib64/pkgconfig/libcap.pc' file? It looks broken.
Have the same problem. Here are the contents of libcap.pc: prefix=/usr exec_prefix= libdir=/usr/lib64 includedir=/usr/include Name: libcap Description: libcap - linux capabilities library Version: 2.29 Libs: -L${libdir} -lcap Libs.private: Cflags: -I${includedir} Name: libpsx Description: libpsx - linux posix syscall API for pthreads Version: 2.29 Libs: -L${libdir} -lpsx -lpthread -Wl,-wrap,pthread_create Libs.private: Cflags: -I${includedir}

Can you share 'emerge --info libcap' as well?

Should be fixed with =sys-libs/libcap-2.29-r1 Please test
> > Name: libcap > > Name: libpsx Also happens for =sys-libs/libcap-2.29-r1 for me. I think the real bug here is that they should live in two different .pc files.
The simplest reproducer is: $ pkg-config --libs libcap Name field occurs twice in '/usr/lib64/pkgconfig/libcap.pc' It should report at least '-lcap'.

Fails with dev-util/pkgconfig Works with dev-util/pkgconf Once I find the time I try to separate the two .pc files

=sys-libs/libcap-2.29-r2 is enough to make =app-misc/pax-utils-1.2.4 build successfully \o/
-r2 fixes it for me too. Thanks everyone! Happy holidays, happy new year!
