Problem installing gtk+ 2.4.1

["Pedro Faria" <quattrocs hotmail com>]

hello
i'm new to the list and semi-new to linux
i have installed linux madrake 9.2 on my laptop
and i am now trying to install airsnort

i have done and installed everything like i was directed, in that same order
installed kernel 2.4.26
pcmcia-cs drivers
wlan-ng
libpcap
next in line is gtk+-2.4 and gtk+-devel
then i can install airsnort

for gtk+-2.4 i installed the dependecies, then glib, now i was going to 
install pango, but it does not see  the glib install

and this is where i am stuck
Please help

lastly where can i find gtk+-devel package

Thanks in advanced
Pedro
