Epiphany does not build on Fedora 14

[Tirtha Chatterjee <tirtha p chatterjee gmail com>]

I downloaded the latest development release of Epiphany 2.31.5 (I
could not download from GIT because it does not wok from my proxy),
and tried to build it with these commands.

$ ./configure --prefix='/home/tirtha/epiphany-2.31.2/build' --enable-debug

Configure gave the following result:

Epiphany was configured with the following options:

	Source code location       : .
	Compiler                   : gcc
	Prefix                     : /home/tirtha/epiphany-2.31.2/build
	Extra debugging support    : yes

 	Zeroconf bookmarks support : no
 	NetworkManager support     : no
 	GObject introspection      : yes
 	Seed support               : no
 	NSS support                : yes
	Build tests		   : yes
	CA Certificates file	   : /etc/pki/tls/certs/ca-bundle.crt

Even when I disable GObject introspection, the same error occurs
during make. What is the problem here? Can anyone please suggest me
how to fix it?
