[R] shared libraries on FreeBSD 4.*

[loren mccarter]

Thanks for your help. As was suggested by Prof Ripley, the problem appears
to be related to the environment variables for FLIB, LIBS and
LD_LIBRARY_PATH. I was able to solve the problem with RODBC by setting the
LIBS variable in the current shell immediately before the install (LIBS
was already set correctly in $RHOME/etc/Makeconf but RODBC must not
have been reading it). Below is a log that might be useful for
understanding the issue. It uses a modified version of the RODBC/configure
script that simply prints to screen the relevant environment variables
before AC_SEARCH_LIBS is invoked. I have yet to figure out what's
happening with RSPython, but that is probably more approporate for
omegahat-help if Prof Ripley's suggestion does not work. Thanks!

Loren
