export GDS 2

[Rob Chapman]

 Whenever I try to export a layout in GDS 2 format, I get an error
 message:

java.lang.NoSuchMethodError: java.math.BigDecimal.<init>(I)V

 I'm running on Mac OS X.4.3 with Java 1.4.2 and J2SE5.0 selectable. 
Why would a
 method be missing?  Am I missing a java library?  I'm ecstatic to finally
 be able to design actual hardware on a Mac after waiting for many years and
 now I'm so close!  Any insights are appreciated.
