ports/102474: linux_base-fc-4_8 appears broken, does not allow to run Linux binaries

[Scott T. Hildreth]

Well I am trying to follow the threads, I know I am missing something 
here.  To make sure I removed all linux packages.  I reinstalled, I do 
get this link created by the linux_base-fc4 or linuxpluginwrapper is
creating it.

lrwxrwxrwx  1 root  wheel  19 Aug 29 20:52 /usr/compat/linux/lib/libpthread.so.0 -> libpthread-2.3.6.so

Then I can run acroread, but the browser plugins aren't working.  
The errors messages are,

LoadPlugin: failed to initialize shared library /usr/local/lib/npapi/linux-flashplugin/libflashplayer.so [Shared objec
t "libpthread.so.0" not found, required by "libflashplayer.so"]

...my head is swimming now, I can't figure out why libpthread.so.0 cannot not be found.

LoadPlugin: failed to initialize shared library /usr/X11R6/Adobe/Acrobat7.0/ENU/Browser/intellinux/nppdf.so [/usr/X11R
6/Adobe/Acrobat7.0/ENU/Browser/intellinux/nppdf.so: Undefined symbol "__ctype_b_loc"]
