Uhm for my sins, I've got:
root at selfservice:/usr/local # uname -a
SunOS selfservice 5.10 Generic_142901-07 i86pc i386 i86pc
oot at selfservice:/usr/local # file /usr/local/oracle/product/instantclient_10_2/ 
/usr/local/oracle/product/instantclient_10_2/ ELF 32-bit LSB dynamic lib 80386 Version 1, dynamically linked, not stripped
root at selfservice:/usr/local #
... and I think what makes it possible:
root at selfservice:/usr/local # file /usr/local/bin/perl
/usr/local/bin/perl:    ELF 32-bit LSB executable 80386 Version 1 [FPU], dynamically linked, not stripped, no debugging information available
root at selfservice:/usr/local # 

Which was either from or locally built.

On some SPARC systems where there's a full 64bit Oracle installed, I've
resorted to ensuring that I've set
before starting or where I can't/don't trust the environment to:
  # needs to before loading the DB modules
  $ENV{ORACLE_HOME} ||= '/export/home/oracle1020/product/1020/client_1';
  # LD_LIBRARY_PATH needed because we're on a 64bit Oracle now
  $ENV{LD_LIBRARY_PATH} ||= "$ENV{ORACLE_HOME}/lib32:$ENV{ORACLE_HOME}/network/lib32";
But again this is with a 32-bit Perl.
# file /usr/local/bin/perl
/usr/local/bin/perl:    ELF 32-bit MSB executable SPARC Version 1, dynamically linked, not stripped

Install a 32-bit Perl has been my solution.  I'll need to look at
this again soon for the next technology refresh though :-/  

I'm hoping it won't be as irritating on RHEL/OUL, but my first attempts
to setup an application server for Oracle 11g ended up rebuilding the
whole system as 32-bit because the application vendor had linked their
app against a 32-bit libclntsh and 32-bit Oracle 11g won't install on a 
64-bit o/s ...
