It seems the BLAS path is incomplete. Please run otool -L on your .so -- if compiled correctly you should see something like

ginaz:library$ otool -L KernSmooth/libs/x86_64/KernSmooth.so
KernSmooth/libs/x86_64/KernSmooth.so:
	KernSmooth.so (compatibility version 0.0.0, current version 0.0.0)
	/Library/Frameworks/R.framework/Versions/2.13/Resources/lib/libRblas.dylib (compatibility version 0.0.0, current version 0.0.0)
	/Library/Frameworks/R.framework/Versions/2.13/Resources/lib/libgfortran.2.dylib (compatibility version 3.0.0, current version 3.0.0)
	/Library/Frameworks/R.framework/Versions/2.13/Resources/lib/libR.dylib (compatibility version 2.13.0, current version 2.13.1)
	/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 476.19.0)
	/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 111.1.5)

If in doubt, compile your package with reference BLAS and then switch to vecLib BLAS - I suspect that will work.

Cheers,
Simon
