Missing libraries when installing EM Grid Control

When I was trying to install and setup an Enterprise Manager Grid Control 10g R2 (10.2.0.1.0) on an Oracle Enterprise Linux 4 (OEL4) platform, I surprisingly found I didn't meet the package list install requirement, it stated there were three libraries missing, I did install and reinstall them from the OEL4 disks, unsuccessfully, since the error still persist. I should have STWF (Searched The Web First) for further cases where something curious like this had happened to somebody( Linux OEM Grid Control 10.2.0.1.0 installation issue), and yes, it happened to this individual who was very kind in documenting this at the Oracle forums.

The error is found with these three missing RPM's:

• compat-libstdc++-296-2.96-132.7.2 (failed)
• libstdc++devel-3.4.3-22.1 (failed)
• openmotif-21-2.1.30-11 (failed)

It can be seen that openmotif-21 is misspelled, it should read openmotif21, without the hyphen.
I did further search at Metalink [Note:343364.1, Prerequisites and Install Information for EM 10g Grid Control Components on Red Hat EL 4.0 Update 2 (and higher updates) Platforms] and I found that when installing EM Grid Control with a fresh database on 10g, it always shows this library error. Experience always comes when it is no longer required. The installer has a flaw, so it will show an error even if the three missing libraries are installed on the system, it is because a bad list of RPM's in the installer. This error can be user checked and proceed with installation, it will succeed. Just, this error is ever found, I suggest to proceed with caution, and make sure the list of RPM's meet the minimum requirements, if this manual check is successful, the missing RPM's error can be skipped.
