SeLinux Checkpolicy install error ( /usr/bin/ld: cannot find -lfl)

Question

I am trying to setup selinux per the arch wiki, but I ran into an error when trying to install the checkpolicy package from the AUR. I keep getting the following error:
==> Starting build()...

  /usr/bin/ld: cannot find -lfl
  collect2: error: ld returned 1 exit status
  <builtin>: recipe for target 'checkpolicy' failed
  make: *** [checkpolicy] Error 1
any ideas? I have been googling for a few hours trying to find out about the -lfl and to see if i am missing it , but cannot figure this out. I downloaded the tar for checkpolicy and have the same issue.
Should I be altering the makefile in anyway so that /usr/bin/ld can find -lfl ?

Answer 1

@Allan: The selinux-flex package is needed as part of the installation process.
Something tells me that this AUR package needs to be updated.
But yes, a solution appears to be to remove selinux-flex and install flex and then compile checkpolicy.
