There's the first error. It can't open /usr/include/mach/machine.h  
due to an input/output error. That usually only occurs if your disk  
is failing! Can you open this file manually? I expect not. You should  
back up your data immediately, preferrably onto a second set of  
backup media so that you don't overwrite a previous backup, in case  
the disk is already gone. I'm not sure how best to test the disk, but  
you can try verifying the disk in Disk Utility and also check its  
S.M.A.R.T. status at the bottom of the Disk Utility window. A healthy  
disk should have the status "verified".
