lvm2 flag problem

[radek]

 The ebuild selected to satisfy "sys-fs/lvm2[static]" has unmet requirements.
- sys-fs/lvm2-2.03.24::core-kit USE="lvm readline static udev -sanlock (-selinux) -static-libs -thin -valgrind"                                                                   

  The following REQUIRED_USE flag constraints are unsatisfied:
    static? ( !udev )

  The above constraints are a subset of the following complete expression:
    static? ( !udev ) static-libs? ( static ) thin? ( lvm )

i set flag

# required by sys-kernel/genkernel-4.0.3-r3::core-kit
# required by sys-kernel/debian-sources-lts-5.10.158_p2::core-kit[binary]
# required by @selected
# required by @world (argument)
>=sys-fs/lvm2-2.03.24 static

try setting flag
sys-fs/lvm2 static -udev

 

EDIT: i believe static? ( !udev )  means if static is set udev must not be set
