Has anyone succeeded to install postgresql-devel-8.3.23-0.4.1 on SLES11SP3?

I'm stuck with this error:

# rpm -ivh postgresql-devel-8.3.23-0.4.1.x86_64.rpm
error: Failed dependencies:
libecpg6 = 8.3.23 is needed by postgresql-devel-8.3.23-0.4.1.x86_64
libpq5 = 8.3.23 is needed by postgresql-devel-8.3.23-0.4.1.x86_64

Thanks in advance for your help.
