conky: emerge update fail

[ser]

From many time i can't update conky from the installed version 1.11.1 to the updated 1.11.3.

There is this configuration error:

Checking for one of the modules 'lua>=5.3;lua5.3;lua-5.3;lua53;lua5.2;lua-5.2;lua52'
CMake Error at /usr/share/cmake/Modules/FindPkgConfig.cmake:659 (message):
  None of the required 'lua>=5.3;lua5.3;lua-5.3;lua53;lua5.2;lua-5.2;lua52'
  found

I don't know what to do.
