Error compiling SVN from raptor.h

A very non-descript error that stops the compiler:

In file included from libs/ardour/
/usr/include/lrdf.h:8:20: error: /usr/include/raptor.h: Input/output error
scons: *** [libs/ardour/audio_library.os] Error 1
scons: building terminated because of errors.

configure ran without errors, I started all this with a jack svn compile and scons -c, then scons VST=yes

never mind. my disk is broken. fuck.
