FWIW, I don't use MacPorts, but i do subscribe to the mailing list. SuiteSparse provides CHOLMOD. SuiteSparse is listed as a dependancy in the octave Portfile. You might want to post this question to the macports-users list.

Hi,  I am not exactly if this is the correct place to ask this  
question or not - my apologies if misplaced.

I just installed octave 2.9.9 using darwinports and tried to run a  
small matrix test case for matlab (mytrit.m from Johan Helsing of  
Lund University).  When I try to run it, it gets to the line:


and I get the error message:

     error: Missing CHOLMOD. Sparse cholesky factorization disabled

[If I comment out that section, everything else seems to run fine.]

Now as near as I can tell cholmod should be part of SuiteSparse  
(which was also installed [v. 2.4.0_0] as part of this process).  The  
headers for cholmod are found in "/opt/local/include/ufsparse".   
There is also a chol.oct found in "/opt/local/libexec/octave/2.9.9/ 

Unfortunately, the I did not try to build it verbose - and cannot  
find any log or error files that might point out what actually  
happened.  Does anyone have any ideas on what I possibly did wrong  
and how I might fix it?

I have a copy of 2.1.73 which was installed from binaries provided by last year in /usr/local/bin - but /opt/local/bin  
comes first in my path.  I had originally tried to install the 2.9.9  
binaries from there, but it complained because I did not have UMFPACK  
(probably because I did not have ufsparse at that time).

Thank you for your time.
