Seems like there is no slang.h installed. Could you please check:
$ find /usr/include/ -name slang.h
On my FC17:
$ find /usr/include/ -name slang.h
/usr/include/slang/slang.h
/usr/include/slang.h
$ rpm -qf /usr/include/slang.h
slang-devel-2.2.4-3.fc17.x86_64
$ rpm -qf /usr/include/slang/slang.h
slang-devel-2.2.4-3.fc17.x86_64

And does 'export SLANG_INC=<to location of the slang.h>' works any
better? :)
