Below is an exchange from the mozilla.dev.builds newsgroup. A brief
statement of the problem is SeaMonkey quits building with a:

No rule to make target `-lpthread', needed by `libmozjs.so'. Stop.

Well:

$ locate libpthread.so | xargs ls -l
lrwxrwxrwx 1 root root 20 2010-06-01 16:58 /lib64/libpthread.so.0 ->
libpthread-2.11.1.so
-rw-r--r-- 1 root root 222 2010-05-13 01:15 /usr/lib64/libpthread.so

$ gcc -v

Will do, thank you.

Anyone shed some light on this?

is this (libpthread.so) a symlink pointing to libpthread-2.11.1.so ?

If so, it should work...

This looks right; while compiling does it say -L/usr/lib64 ?

Was not; is now. Running a compile....

Same failure.

No. Do you know how to add this permanently? Is this possibly a result
of having upgraded 13.0 to 13.1 without doing a fresh install?

Sample stanza:

libtool: compile: gcc -DHAVE_CONFIG_H -I.
-I/home/Rinaldi/tmp/Mozilla/comm-central/mozilla/js/src/ctypes/libffi
-I.
-I/home/Rinaldi/tmp/Mozilla/comm-central/mozilla/js/src/ctypes/libffi/include
-Iinclude
-I/home/Rinaldi/tmp/Mozilla/comm-central/mozilla/js/src/ctypes/libffi/src -Wall
-g -fexceptions -g -O2 -MT src/debug.lo -MD -MP -MF src/.deps/debug.Tpo
-c
/home/Rinaldi/tmp/Mozilla/comm-central/mozilla/js/src/ctypes/libffi/src/debug.c
-fPIC -DPIC -o src/debug.o
