"pkg-config is already the newest version." :(

If I try to comment the lines in src/host/layer23/configure

PKG_CHECK_MODULES(LIBOSMOCORE, libosmocore)
PKG_CHECK_MODULES(LIBOSMOVTY, libosmovty)
PKG_CHECK_MODULES(LIBOSMOGSM, libosmogsm)
PKG_CHECK_MODULES(LIBOSMOCODEC, libosmocodec)

I've an include error:

l1ctl.c:33:41: fatal error: include/osmocom/core/signal.h: No such file or directory
compilation terminated.

signal.h exists into src/shared/libosmocore/include/osmocom/core/signal.h

:(
