 Due to an upstream configure bug on Macs, HDF5's configure disables the
 building of shared libraries if the --disable-fortran configure option is
 given.

 The patch shipped with the current port works around this bug partially,
 but not completely (only some shared libraries are being built).

 Replacing the current patch (patch-configure.diff) with the one attached
 to this ticket works at least on my machine (OS X 10.5).

 ----

 Explanation of the problem:

 Currently the file config/apple (in the HDF5 archive) checks if the
 variable "enable_fortran" is non-empty, if it is, shared libraries are
 disabled.  With the --disable-fortran configure option, this variable is
 set to "no", so the test returns true, also disabling the building of
 shared libraries.  The attached patch now tests the value of the variable
 against "yes", only then shared libraries are disabled, yielding the
 correct behavior.
