DBD-Oracle Compilation error on OpenVMS

I have installed DBD-Oracle on an OpenVMS IA64 box.

Versions:

oracle 10.2.0.4 (Client - Db is 11.1.0.7 on solaris)
DBI 1.615
DBD 1.26
Perl 5.8.6


It is as such completed, but I got this error on the way:

This may well be an OpenVMS problem, that an external identifier name 
must not exceed 31 charachters ?

What I did was replace all occurrencies of

         dbd_phs_ora_varchar2_table_fixup_after_execute

with

         dbd_phs_ora_varchar2_table_fea
in

         DBDIMP.C

which helped a lot.

Is this a known problem? or a serious one ?
