FYI, that solution actually solves a similar problem, the one evidenced by this error:

install_driver(Oracle) failed: Can't load
'/usr/local/lib/perl5/site_perl/5.005/i386-linux/auto/DBD/Oracle/Oracl
+e.so'
for module DBD::Oracle: ld.so.1:/usr/local/bin/perl: fatal:
libclntsh.so.8.0: open failed: No such file or directory at
/usr/local/lib/perl5/5.00503/i86pc-solaris-thread/DynaLoader.pm
line 169.

This error occurs when all the DBD::Oracle files are found, but the main Oracle libraries aren't. In the original poster's case the DBD::Oracle files weren't found (this problem actually isn't as common, though).
