Strange flash issue on Current 9.0 that I am not seeing on stable 7.3

[Edwin L. Culp W.]

On 9.0-CURRENT FreeBSD 9.0-CURRENT #67: Fri Sep  3 07:11:34 CDT 2010 I
get the following with Firefox when trying to view a youtube video:

# firefox3
LoadPlugin: failed to initialize shared library
/root/.mozilla/plugins/nppdf.so [Shared object "libc.so.6" not found,
required by "nppdf.

I get basically the same error with chrome:

*** NSPlugin Viewer  ***

I have no problem on:
 7.3-STABLE FreeBSD 7.3-STABLE #1117: Fri Sep  3 05:26:11 CDT 2010
Flash works perfectly on both firefox and chrome

I have rebuilt all linux ports with portmaster -r  several times.

It was working fine no more than a week ago but in a reboot, rebuild,
port update or something similar I have lost it completely.

Any suggestions appreciated.

TIA

P.D. linux-opera works as expected.  The following have been rebuilt
today with portmaster -r
