PPPD has ld.so.cache problem

I was having a problem with the arp tables using Linux 1.2.13 allowing over 30 concurrent modem connections.
To fix that problem, I upgraded my kernel to 2.0.33 and the system came backup and the slip connections are functioning properly.  The problem is that the pppd is not functioning. Initially I was getting ppp not available on the system even though it is compiled in the kernel.  The problem I get now is that it reports cache '/etc/ld.so.cache has wrong version' message.

I have tried the strace function to try and locate the answer and it has not been helpful.  I am going to be trying to upgrade the libc, gcc, libg++ and the ld.so in hopes that this might fix the problem.

Thanks for your assistance.

Apparently you have upgraded ld.so but not regenerated
ls.so.cache and the format has changed. As root run
/sbin/ldconfig to fix this problem. This is recommended but not
absolutely vital after installing new libraries or newer versions of a library you have already.
IF you face missing library or linkage problems use
ldd <progname> to figure out which libraries it needs. If this
fails the upgrading to the latest release of the name major
version of the library fixes the problem. IF this fails, due to a bug fix for example, recompiling the pakckage helps (I know this having started wiht 0.99pl13, libc 4 and now using 2.1.88 and libc 6)

Remeber this,
When you recompiled your kernel you should always download and recompile your pppd program all over again.

To Jetx:

Recompiling PPPD after recompiling the kernel was done on more than one occasion and the problem still existed.  Even the steps outlined in the orginal answer were not totally on target, but I was to solve the problem, before I got the original answer.  In part the comment that I added last time, regarding the source of information about which lib's and gcc's etc, are expected to be found with which kernel is still lacking.
