Who packaged Nant as rpm? and Mono? Both should agree on version
numbers, although Mono runtime uses another criteria for version
matching, see further down below...

AFAIK, RPM dependency version-checking won't do what is needed so
maybe a check for any-version of Mono is the best solution.

Two possibilities:

1) The Mono RPM contains the right libraries but was packaged with the
version numbers, or not so fine grained as the error messages seem to
indicate the Nant package wants.
2) Mono is using version policies to load newer versions of the
libraries. Version policy files tell Mono Assembly loader that a newer
version of a library is safe to be used in any place one from a range
of older versions is requested.

Mono nowadays packs the .NET 1.1 libraries (Version=1.0.5000.0) that
are compatible with the .NET 1.0 libraries (Version=1.0.3300.0). So
adapt your script to add a rpm provides for each 1.1 library you pack.
A better, but more complex solution, is to look at the version policy
files being packed to be sure what manual provides should be issued.

The ultimate solution would be Nant to be packaged asking for version
>= 1.0.3300.0 of Mono Libraries, as the runtime already knows what to
do as instructed by the version policy files.

Hope it helps,
