clex 3.18 failing on PPC

[Manuel Wolfshant]

Hello

    Kairo Araújo - whom I have sponsored - has tried to update the 
package "clex" to version 3.18 
(http://koji.fedoraproject.org/koji/taskinfo?taskID=585648 ). 
Unfortunately build for PPC (and only for PPC) fails in koji, as can be 
seen at http://koji.fedoraproject.org/koji/taskinfo?taskID=585651 (this 
happens both in rawhide and F9). The build log ends with

checking dependency style of gcc... 
gcc3
checking for library containing stdscr... 
no
configure: error: CLEX requires NCURSES package

The same configure script on PPC64 gives:

checking dependency style of gcc... 
gcc3
checking for library containing stdscr... 
-lncurses

(and builds successfully, unsurprisingly)
    ncurses-devel in an explicit BR and according to 
http://koji.fedoraproject.org/koji/getfile?taskID=585651&name=root.log 
it has been installed in the buildroot.
    Since neither Kairo nor I have access to PPC based machines, could 
someone give us a hand, please ?
