linux port: Apache License Version 2.0 question

[Alexander Logvinov]

Hello!

 I am creating a port for a dedicated server which is built for Linux. This executable file requires
to launch Apache xerces-c 2.7 library built for Linux, that is why (following the bsam@'s advice)
I've written linux-xerces-c2 port which installes libxerces-c.so.27.0 from xerces-c-2.7.0-1.2.fc4.rf.i386.rpm 
which had been found here:
http://ftp.belnet.be/packages/dries.ulyssis.org/fedora/fc4/i386/RPMS.dries/xerces-c-2.7.0-1.2.fc4.rf.i386.rpm . 

 Everything works, but there is an issue concerning Apache License, Version 2.0 for xerces-c.
What are the conditions for making a port of linux-xerces-c2 and making a package from it?
LICENSE.txt file is present in the rpm and is copied to /usr/share/doc/. Is this enough?
