ports-all

ms#

i do cvsup and get a lot of errors:

Updating collection ports-all/cvs
Cannot calculate checksum for "/usr/ports/devel/boost/pkg-plist": 
Input/output error
Cannot calculate checksum for 
"/usr/ports/devel/clint/files/patch-python.h": Input/output error

After cvsup ends i cannot install php4 port.Seems like Makefile is broken:

"Makefile", line 125: warning: " -q MPM_NAME" returned non-zero status

Something happened to ports tree ?
