=========== WARNING ===========
|
|
|
|
You are building this extension on OS X without setting the
|
|
ARCHFLAGS environment variable, and BerkeleyDB does not appear
|
|
to have been built as a universal binary. If you are seeing this
|
|
message, that means that the build will probably fail.
|
|
|
|
Try setting the environment variable ARCHFLAGS
|
|
to '-arch #{arch}' before building.
|
|
|
|
For example:
|
|
(in bash) $ export ARCHFLAGS='-arch #{arch}'
|
|
(in tcsh) % setenv ARCHFLAGS '-arch #{arch}'
|
|
|
|
Then try building again.
