BX is known to crash when run on RH Linux 7.3 if the environment variable LANG is set to en-US.iso885915 and you are running BX on a foreign X server. More information on this bug in Red Hat can be found https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=62844. To work around it, please set your environment variable LANG to en_US. For example, if you are using the csh shell you would type:
% setenv LANG en_US

After installation, I run BX on SUN Solaris, but I got an error message like: bxb: fatal: libCrun.so.1 version 'SUNW_1.2' not found.
You need to install a patch on your system. They are available from Sun.com web site. The patch numbers are

108434-17 (if you are using Solaris 8)
111711-11 (if you are using Solaris 9)

These patches will provide the libraries that are needed by BX.
