Hi Brice,

I'm sorry for the double report. Now when you wrote it I remember that I
have reported it:-)

Thanks for fixing the man page.

I have one more question: RHEL has splitted hwloc into 2 subpackages
* hwloc
* hwloc-gui (it contains merely lstopo)

The former one does not need any X11 dependencies.

I have now tried to do the same for Fedora but it's not so easy. On Fedora
I build the package with libXNVCtrl but libXNVCtrl needs libX11. So even
CLI tools need libX11:

ldd lstopo-no-graphics => (0x00007fffbf1cb000) => /dev/shm/usr/lib/ (0x00007f7a5277c000) => /lib64/ (0x0000003c06a00000) => /lib64/ (0x0000003c05e00000) => /lib64/ (0x00007f7a52545000) => /lib64/ (0x0000003c07a00000) => /lib64/ (0x0000003c07600000)

Is there any way around? (On RHEL it's easy. RHEL does not provide
libXNVCtrl at all so the package is built without it.
Then lstopo-no-graphics does not depend on libX11)

I currently see two options:
A) Accept the fact that lstopo-no-graphics depends on X11. The number of
dependencies for lstopo (from hwloc-gui package) is still much lower
compared to lstopo-no-graphics
B) Compile it without libXNVCtrl but it will reduce the functionality.

Is there any 3rd option? I guess not. It seems like A) is the best choice
for Fedora.

Any ideas on that?
