Guile cannot found lib libguilereadline-v-17

I want to use readline (use-modules (ice-9 readline)). It's work in linux system.

I have this back trace when i write this command in .guile file

Backtrace:

It may be an interaction between guile and libltdl; if you try

$ env LTDL_LIBRARY_PATH=/opt/local/lib guile

Then try your use-modules, if it works, then we need to figure out how to get guile/libltdl to always look there (there are several ports, gnucash being one, which have a wrapper script to set this environment variable at the moment).

ok, it's working.

Seems like an appropriate rpath during linking might help?

I had a brief look at trying to add an rpath to guile compilation (-Wl,rpath,/opt/local/lib), but it didn't seem to help. Since there is mention of it being a libtldl issue perhaps it needs to be given the rpath?

Really old, likely fixed. Please reopen if you have issues.
