asterisk users - Feb 2014 - Problem/error with DAHDI tools 2.9.0.1

Hello,

Getting this error on dahdi_cfg. Reverting to 2.8 the error goes away:

*line 15: Unable to create 'dahdi_cfg' mutex.*

Is this a problem?

Thanks in advance.

Which distro / version are you running? It appears that the sem_open
call has failed on this platform.

There does appear to be a mistake in the code though with the error
reporting. 'perror' should be used instead of 'error'.  The line
number in the config file isn't related to this error report.
