I've searched and not found reference to my specific error, but if there is one I'll apologize in advance.
Here goes:
I have successfully installed kdenlive 0.7.8 from source on both my home AMD 64 dual core pc, and my Dell D820 Latitude laptop, both running openSUSE 11.3 and it is great. Everything works. Unfortunately, I cannot get a fully successful installation on my Mac 15" laptop with Intel processor, OS is 10.5.8 fully up to date.
My first attempt(s) were with the MacPorts package. This installed kdenlive, but with problems such as no themes except the default, then after rendering for DVD I could not make movie menu nor create an iso DVD after going back and skipping the make movie menu.
So, I uninstalled MacPorts and went the route of installing MacPorts from SVN. After hours of compilation, it finally ended with the following:
:msg:main ---> Dependencies to be installed: mlt libsamplerate sox
:debug:main Starting logging for libsamplerate
:error:checksum The following dependencies were not installed: mlt libsamplerate sox
:error:checksum Status 1 encountered during processing.
Neither sox nor mlt would install because of the checksum error with libsamplerate. Doing sudo port -v install libsamplerate produces the following:

I have even downloaded and installed the libsamplerate tarball, but I am not sure how to get it properly recognized to complete the mlt and sox installations.
Any ideas?
Thanks,

Here's an update to the above post. Since nothing I tried worked, I uninstalled all of MacPorts, cleaned up the directories, and then reinstalled MacPorts this time from source. Same thing. Cannot install mlt or kdenlive because of the checksum failure with libsamplerate. This one corrupt checksum prevents sox from installing as well. It is my opinion that until it is fixed within MacPorts, kdenlive cannot be installed on a Mac OS X. I am sure that the same scenario will occur if I use the dmg package to install MacPorts, but if necessary I don't mind trying. I just think that, for now, I'll wait for news about the libsamplerate checksum.
Thanks,
Mark
