./configure fails in xffm

[Wally Brock]

I've succesfully compiled all of the modules except xffm

Every time I run autogen.sh or configure I always get the same error:

./configure: line 9260: syntax error near unexpected token `PACKAGE,'
./configure: line 9260: `PKG_CHECK_MODULES(PACKAGE, $pkg_modules)'

System is running RedHat 8.0

Thanks in advance for any help !
