build failed to complete

[Gérard Milmeister]

This is the build log for graveman on i386:
http://extras64.linux.duke.edu/failed/4/graveman/0.3.12.4-1.fc4/i386/graveman-0.3.12.4-1.fc4.failure.log
It says:
checking for mng_read in -lmng... yes
checking libmng.h usability... no
checking libmng.h presence... no
checking for libmng.h... no

This is strange, since the .spec file contains:
BuildRequires:  libmng-devel
