[gentoo-user] X11 specific libs not used/found

[Valmor F. de Almeida]

Hello,

I am trying to install a data visualization package (VisIt) which 
installs locally, on its own, a qt package (qt-everywhere-src-5.14.2). 
The config output says:

[snip]

  X11 specific:
    XLib ................................. no
    XCB Xlib ............................. no
    EGL on X11 ........................... no

[snip]

  XCB:
    Using system-provided XCB libraries .. no
    XCB XKB .............................. yes
    XCB XInput ........................... yes
    Native painting (experimental) ....... no
    GL integrations:
      GLX Plugin ......................... no
      EGL-X11 Plugin ..................... no

which indicates that later during install of the whole package, some XCB 
files are not found.

I have installed libX11, and xorg-x11. Apparently some libx11-dev 
package is needed but I don't seem to find it in Gentoo.

Any help appreciated.
Thanks,
