AFAICT these patches have been applied in Debian since they have been
committed into your CVS repository, and no bug has been reported, so
you do not have to worry too much ;)
Something goes wrong, but I am not even sure it is related to cmake
(it may be a Java problem too, or a broken autobuilder), I was asking
just in case Modestas or others had been experiencing similar
problems.

I will try to have access to an ia64 box tonight, but
   https://buildd.debian.org/fetch.cgi?pkg=gdcm&arch=ia64&ver=2.0.14-9&stamp=1273082198&file=log&as=raw
contains a successful check:
  -- Java version 1.6.0.18 configured successfully!
  -- Found Java: /usr/lib/jvm/default-java/bin/java
  -- Found JNI: /usr/lib/jvm/default-java/jre/lib/ia64/libjawt.so
so it looks like CMAKE_SYSTEM_PROCESSOR should be set to ia64.
