When trying to emerge povray, the compilation process gets all the way through until it comes time to link into a binary. An undefined reference error then occurs because it's expecting a -lpthread. I have included a diff. Reproducible: Always Steps to Reproduce: 1. emerge povray 2. Wait for compile to complete Actual Results: The following error occurs: g++ `if [ "Xgcc" = "Xgcc" ]; then echo "-Wno-multichar"; fi ` -static -I/usr/X11R6/include -o povray atmosph.o bbox.o bcyl.o benchmark.o bezier.o blob.o boxes.o bsphere.o camera.o chi2.o colour.o colutils.o cones.o csg.o discs.o express.o file_pov.o fncode.o fnintern.o fnpovfpu.o fnsyntax.o fpmetric.o fractal.o function.o gif.o gifdecod.o hcmplx.o hfield.o histogra.o iff.o image.o interior.o isosurf.o jpeg_pov.o lathe.o lbuffer.o lightgrp.o lighting.o matrices.o media.o mesh.o normal.o objects.o octree.o optin.o optout.o parse.o parsestr.o parstxtr.o pattern.o pgm.o photons.o pigment.o planes.o png_pov.o point.o poly.o polygon.o polysolv.o pov_mem.o povms.o povmscpp.o povmsend.o povmsrec.o povray.o pov_util.o ppm.o prism.o quadrics.o quatern.o rad_data.o radiosit.o ray.o render.o renderio.o sor.o spheres.o sphsweep.o splines.o statspov.o super.o targa.o texture.o tiff_pov.o tokenize.o torus.o triangle.o truetype.o txttest.o userdisp.o userio.o vbuffer.o vlbuffer.o warps.o unix.o povxlib.o -L/usr/X11R6/lib -ltiff -ljpeg -lpng -lz -lm -lX11 -ldl /usr/X11R6/lib/libX11.a(XlibInt.o)(.text+0x4a): In function `_XEventsQueued': : undefined reference to `pthread_equal' /usr/X11R6/lib/libX11.a(XlibInt.o)(.text+0x40e): In function `_XEventsQueued': : undefined reference to `pthread_equal' /usr/X11R6/lib/libX11.a(XlibInt.o)(.text+0x427): In function `_XEventsQueued': : undefined reference to `pthread_equal' /usr/X11R6/lib/libX11.a(XlibInt.o)(.text+0x443): In function `_XEventsQueued': : undefined reference to `pthread_equal' /usr/X11R6/lib/libX11.a(XlibInt.o)(.text+0x460): In function `_XEventsQueued': : undefined reference to `pthread_equal' /usr/X11R6/lib/libX11.a(XlibInt.o)(.text+0x4f6): more undefined references to `pthread_equal' follow collect2: ld returned 1 exit status make: *** [povray] Error 1 !!!

I would appreciate feedback if I did anything wrong, otherwise I'll make the same mistake in the future and waste more of people's time.

It is a bit strange that X11 needs pthreads, but not that strange as I know it can be thread aware. I will change the fix, so it only adds pthread library if X is used. Anyway, I have added the fix, many thanks. If only all bug reports were like this! Please test, and close bug if it works. Stefan
It works now, thanks.
