how to make libtool link with static system libraries instead of dynamic

[Andy Falanga (afalanga)]

I am wondering how I would make libtool link with static versions of already 
installed libraries instead of the dynamic ones.  I have something like this in 
Makefile.am

pyexec_LTLIBRARIES = mylib.la
mylib_la_LDFLAGS = -Wl,-Bstatic
mylib_la_LIBADD = -lz -lrt -lboost_python ....

The problem is, all of the -l options appear before the -Wl,-Bstatic.  This 
means that the dynamic libraries are linked.  How do I make this happen?

Thanks,
Andy
