>Description:
When trying to build x11/startup-notification from pkgsrc-current, configure 
step fails with:

[...]
checking for connect... yes
checking for remove... yes
checking for shmat... yes
checking for IceConnectionNumber in -lICE... yes
checking if malloc() and friends prototypes are sn-util.h compatible... yes
checking whether realloc (NULL,) will work... yes
checking execinfo.h usability... no
checking execinfo.h presence... no
checking for execinfo.h... no
checking pkg-config is at least version 0.9.0... yes
checking for xcb... yes
checking for xcb_aux... yes
checking for xcb_event... yes
checking for x11_xcb... no
configure: error: Cannot find x11-xcb
*** Error code 1

This is with native X.Org; I can't find any libx11-xcb mention in 
usr/X11R7/lib*.


>How-To-Repeat:
Update to pkgsrc-current
Try to build x11/startup-notification.
>Fix:
Not known yet.
