The placeholders added to sample configuration files are not replaced when generating RPMs

I'm working on a branch named xml-collector and I added some sample configuration files and scripts (to automatically generate the configuration files for 3GPP XML Data). I used some placeholders to those files as we usually do on opennms-base-assembly.

I've generated the RPMs, I've installed the file opennms-plugin-protocol-xml-1.9.94-0.20111128.0.noarch.rpm, and the sample files still shows the placeholders and they were not replaced with the proper value.

Here are some sample of the placeholders I'm using:

etc/xml-datacollection-config.xml:

<xml-datacollection-config rrdRepository="${install.share.dir}/rrd/snmp/" xmlns="http://xmlns.opennms.org/xsd/config/xml-datacollection">

contrib/xml-collector/3gpp-datacollection-generator.pl

#!${install.perl.bin}
...
my $share_dir = "${install.share.dir}";
