Psensor v0.6.2.15 has been released and fixes few issues concerning the code portability on CentOS and Kfreebsd.
Psensor should now working fine on CentOS 6. Psensor-server compilation requires some packages which are not available in the official repositories but it has been reported that you can get them from the EPEL repositories. Thanks to Joe Henley for his help on fixing CentOS issues.
Psensor can be compiled on Kfreebsd 6 but unfortunely this distribution does not support lmsensor, hddtemp and xnvctrl, so it can only be used to remotely monitor another computer running psensor-server. Psensor-server is compiling fine but cannot be run due to gtop_get_swap not implemented. Not very useful, but compilation on kfreebsd was required to push psensor to the Debian packages repository of the Linux port.
The v0.6.2.15 binary packages for Debian are available in the unstable repository, you can also get them from: http://packages.qa.debian.org/p/psensor.html.
