We are no longer building mothur using 10.5, instead we are using 10.6.4. What version of the Mac OS are you using? You could try downloading the source code for mothur, and building it yourself. It’s fairly simple. You download the source and unzip it. You may want to take a look at the makefile options, http://www.mothur.org/wiki/Makefile_options. Then open a terminal window and cd into the directory containing the source. Then type make, and mothur will build.
I hope this helps,

It’s the same with 32 bit version, just for info.
And as I’m new to the process…
Then open a terminal window and cd into the directory containing the source. Then type make, and mothur will build.
returns:
-bash: make: command not found
Can you please add an instruction on how to make 1.14 work on our 10.5 - I’d be very excited to try out the new features 
It sounds like you either don’t have make installed or don’t have make in your path. We should probably check to make sure you have a compiler as well. Can you tell me what you get when you type: which make and which g++?
We re-built the mac exes using 10.5.8 and posted them to the wiki.
It seems, I didn’t have make installed.
Upgrading to OS X 10.6 solved both problems in one hit
