Recent problem building on OSX, any one else seeing this?

Wasn’t sure if this was the right place to post this, but didn’t see a forum dedicated to building / source code.

scons: *** [/Users/ichabodcole/Sandbox/Blender/svn/bf-blender/trunk/build/darwin/intern/smoke/intern/FLUID_3D.o] /usr/include/secure/_string.h: Input/output error

I have just recently started getting the above error when I try to build blender from source using scons (both in trunk, and branches I build). I’m on an iMac with Snow Leopard. The only recent change that I’ve made was that I reformatted my harddrive / reinstalled OSX. The issue started showing up a bit after that, so there might be a correlation,… or not.

The only solution I have found is doing scons --clean, which clears the problem up, but of course takes forever to build then.

Anyone experiencing this, or have any ideas what the error means?

thanks for any help!
