hey, so i looked into this today (sorry for the delay). libmatio seems to have some linking issues with hdf5 by default, and their bug might not have been resolved.

What I looked into first is to see if the dylibs have properly generated dependencies:
otool -L /usr/local/lib/libmatio.dylib
/usr/local/lib/libmatio.dylib:
/usr/local/lib/libmatio.2.dylib (compatibility version 3.0.0, current version 3.2.0)
/usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.5)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1197.1.1)

and turns out hdf5 is completely missing from that (I made sure that I am building with hdf5 support, and my makefile said so at the end).
However, when I looked at the output of nm: nm /usr/local/lib/libmatio.dylib
it did indeed point me to a bunch of hdf5 symbols that is should be linking aginst, but isn't.

Anyways, to conclude. This seems to be an upstream matio bug. (for example if you run matio's test-suite, you will see all the hdf5/MAT73 tests fail too).

Your only option here is to just build matio without hdf5 support (./configure --without-hdf5)
