Updated and rebuilt the entire toolchain one piece at a time, seems to 
be that the issue was due to an issue that was fixed in proj in the 
latest release. Serving tiles runs fine now. Proj was 4.4.9, updated to 

As for the make install issue, it was done via root. Here is what the 
output was:

[root at filter mod_tile]# make install
make[1]: Entering directory `/var/src/mod_tile'
make[1]: execvp: /usr/lib/httpd/modules: Permission denied
make[1]: *** [install-modules-yes] Error 127
make[1]: Leaving directory `/var/src/mod_tile'
make: *** [install-recursive] Error 1

The folder /usr/lib/httpd/modules does exist and is the correct 
location, it seems that the make script isn't finding the .so file however.

This is on an x86 based Centos 4.5 server, running Apache 2.2.3. Apache 
was installed using the standard centos rpm's for it, so it should be in 
the normal place (and I've never had issues compiling other extensions 
for it).
