very weird thing net-firewall/pglinux links to net-libs/libnetfilter_queue net-libs/libnetfilter_queue links to net-libs/libmnl as soon as net-libs/libmnl was compiled with clang, pglinux (not libnetfilter_queue) will fail to link with these errors: ===== /bin/sh ../libtool --tag=CC --mode=link x86_64-pc-linux-gnu-gcc -fPIC -march=core-avx2 -O2 -pipe -Wall -Wl,-export-dynamic -Wl,-O1 -Wl,--as-needed -Wl,--hash-style=gnu -o pgld src/pgld.o src/stream.o src/blocklist.o src/parser.o -lnetfilter_queue -lnfnetlink -lz -ldbus-1 -ldl -lpthread /bin/sh ../libtool --tag=CC --mode=link x86_64-pc-linux-gnu-gcc -fPIC -march=core-avx2 -O2 -pipe -Wall -module -avoid-version -Wl,-O1 -Wl,--as-needed -Wl,--hash-style=gnu -o libdbus.la -rpath /usr/lib64/pgl src/dbus.lo -lnetfilter_queue -lnfnetlink -lz -ldbus-1 -ldl -lpthread libtool: link: x86_64-pc-linux-gnu-gcc -fPIC -march=core-avx2 -O2 -pipe -Wall -Wl,-export-dynamic -Wl,-O1 -Wl,--as-needed -Wl,--hash-style=gnu -o pgld src/pgld.o src/stream.o src/blocklist.o src/parser.o -lnetfilter_queue -lnfnetlink -lz -ldbus-1 -ldl -lpthread libtool: link: x86_64-pc-linux-gnu-gcc -shared -fPIC -DPIC src/.libs/dbus.o -lnetfilter_queue -lnfnetlink -lz -ldbus-1 -ldl -lpthread -march=core-avx2 -O2 -Wl,-O1 -Wl,--as-needed -Wl,--hash-style=gnu -Wl,-soname -Wl,libdbus.so -o .libs/libdbus.so Makefile:553: recipe for target 'pgld' failed libtool: link: ( cd ".libs" && rm -f "libdbus.la" && ln -s "../libdbus.la" "libdbus.la" ) make[2]: Leaving directory '/var/tmp/paludis/net-firewall-pglinux-2.3.0/work/pgl-2.3.0/pgld' Makefile:547: recipe for target 'all-recursive' failed make[1]: Leaving directory '/var/tmp/paludis/net-firewall-pglinux-2.3.0/work/pgl-2.3.0' Makefile:458: recipe for target 'all' failed /usr/lib/gcc/x86_64-pc-linux-gnu/4.8.5/../../../../lib64/libnetfilter_queue.so: undefined reference to `mnl_attr_parse' /usr/lib/gcc/x86_64-pc-linux-gnu/4.8.5/../../../../lib64/libnetfilter_queue.so: undefined reference to `mnl_attr_validate2' /usr/lib/gcc/x86_64-pc-linux-gnu/4.8.5/../../../../lib64/libnetfilter_queue.so: undefined reference to `mnl_attr_get_type' /usr/lib/gcc/x86_64-pc-linux-gnu/4.8.5/../../../../lib64/libnetfilter_queue.so: undefined reference to `mnl_attr_validate' /usr/lib/gcc/x86_64-pc-linux-gnu/4.8.5/../../../../lib64/libnetfilter_queue.so: undefined reference to `mnl_attr_put_u32' /usr/lib/gcc/x86_64-pc-linux-gnu/4.8.5/../../../../lib64/libnetfilter_queue.so: undefined reference to `mnl_attr_put' /usr/lib/gcc/x86_64-pc-linux-gnu/4.8.5/../../../../lib64/libnetfilter_queue.so: undefined reference to `mnl_attr_type_valid' collect2: error: ld returned 1 exit status ===== The problem is gone, as soon as net-libs/libmnl was recompiled with gcc.

That wasn't arrogance, I just think it's not possible to understand the bug report just by the given summary. Thanks for enhancing it.
It looks like this is about setting -fvisibility=hidden and then not properly exporting all symbols. You could try with this patch: --- configure.ac.orig 2012-05-18 01:02:27.180568285 +0200 +++ configure.ac 2015-08-17 07:30:34.298280048 +0200 @@ -15,7 +15,6 @@ AC_EXEEXT AC_DISABLE_STATIC LT_INIT -CHECK_GCC_FVISIBILITY case "$host" in *-*-linux*) ;; *) AC_MSG_ERROR([Linux only, dude!]);;
Either that or pglinux is using them when it shouldn't. :)

I get lots of errors with that like socket.c:89:15: error: redefinition of 'mnl_socket_get_fd' as different kind of symbol socket.c:85:5: note: previous definition is here int mnl_socket_get_fd(const struct mnl_socket *nl) and so on.

Next it fails on: ~^ nlmsg.c:241:15: error: redefinition 2 warningof 'mnl_nlmsg_portid_ok' sas different and 2 kind errors of generated. symbol nlmsg.c:237:1: note: previous definition is here mnl_nlmsg_portid_ok(const struct nlmsghdr *nlh, unsigned int portid) ^ nlmsg.c:385:15: warning: type specifier missing, defaults to 'int' [-Wimplicit-int] EXPORT_SYMBOL(mnl_nlmsg_fprintf); ~^ nlmsg.c:385:15: error: redefinition of 'mnl_nlmsg_fprintf' as different kind of symbol nlmsg.c:373:1: note: previous definition is here mnl_nlmsg_fprintf(FILE *fd, const void *data, size_t datalen, and several more redefinitions..
It's a known issue; earlier versions of libmnl are mis-compiled by clang. Please try the latest version (1.0.4). It worked last time I tested it.
