libxml and libxml2

While running configure on libmrproject CVS tree,
I got the following message:
----
configure: error: Library requirements (
        glib-2.0 >= 2.0.4
        libxml-2.0 >= 2.4.7
----

I searched in ftp://ftp.dit.upm.es/pub/GNOME/sources/
for the libxml library.
I found 2 libraries:
- libxml, version goes up to 1.8
- libxml2, version goes up to 2.5

Thus, the 2.4.7 version of libxml
seems not to exist
but it should exist a libxml2 2.4.7 version.

Moreover, as says the web site:
----
Table 1.1. libmrproject dependencies
Package
Version
glib
>=2.0.4
libxml2
>=2.4.7
----
And I had a libxml2 library installed:
----
[j@localhost libmrproject]$ rpm -q libxml2
libxml2-2.5.1-1mdk
[j@localhost libmrproject]$
----

Is there not an error in the configure script
since it confuses libxml and libxml2 ?
