The problem is that some cvs client (filed bug report with supplier) do 
not correctly set executable permissions on scripts, simmilar happens 
when zompressing archives created on other operation systems. CabelSwig 
relies on some scripts for configuration, e.g., 
CableSwig/GCC/config.guess. If those scripts do not have executable 
flags set on Linux, ccmake fails with a critic message 'Cannot find 
gcc_platform.cmake.'.

A workaround is to force executable flags, for instance, using 'chmod -R 
a+x *' in the top CableSwig source directory (after updating from CVS).

There used to be similar issue with early version of ITK/VXL configuration.
