Has anyone tried to port a Subversion client version 1.8.x to QNX 6.5 ?

I understand that Momentics has the Subversive client, but it would be useful to have a native client for scripting 
purposes.   A native subversion 1.6 client is available, but a 1.8 client has better merge support.   I don't need the 
Subversion server ported to QNX, just the client.   Mixing Subversion clients on the same local code files can cause 
problems.

It looks like this would involve compiling two things:

1) The Apache Portable Runtime base portability runtime:

https://apr.apache.org/download.cgi
https://apr.apache.org/compiling_unix.html

2) The 1.8.16 subversion client source code:

https://subversion.apache.org/download.cgi

Any thoughts appreciated.
