>Description:
pkgsrc compiled dbus-daemon is not working due to an invalid binary type (emul 
linux ?!?!?!?!).

>How-To-Repeat:
pkgsrc compile dbus after an update to 5.0_BETA from 4.0_STABLE.
>Fix:
after tacklig a bit with the problems, it seems that the binary generated by 
pkgsrc is wrong when compiled with this option: -Wl,--gc-sections
[...]
cc -ffunction-sections -fdata-sections -O2 -pthread 
-I/usr/pkgsrc/sysutils/dbus/work/.buildlink/include 
-I/usr/pkgsrc/sysutils/dbus/work/.x11-buildlink/include -Wall -Wchar-subscripts 
-Wmissing-declarations -Wmissing-prototypes -Wnested-externs -Wpointer-arith 
-Wcast-align -Wsign-compare -Wdeclaration-after-statement -fno-common 
-Wl,--gc-sections -Wl,-R/usr/X11R7/lib -pthread -Wl,-R/usr/pkg/lib -o 
dbus-daemon-launch-helper activation-helper-bin.o config-loader-expat.o 
config-parser-common.o config-parser-trivial.o desktop-file.o utils.o 
activation-helper.o  -L/usr/pkgsrc/sysutils/dbus/work/.buildlink/lib 
-L/usr/pkgsrc/sysutils/dbus/work/.x11-buildlink/lib -lexpat 
../dbus/.libs/libdbus-convenience.a
[...]

whereas other dbus package binaries not using -Wl,--gc-sections are working 
perfectly, I'm not really sure of the root cause of this, I did not have time 
to investigate much further.


from the same package, dbus-monitor works :

-L/usr/X11R7/lib -Wl,-R/usr/X11R7/lib -pthread -L/usr/lib -Wl,-R/usr/lib 
-Wl,-R/usr/pkg/lib -o dbus-monitor dbus-monitor.o dbus-print-message.o
