Strange that it's complaining about symbols from libicu when the
problem is due to libcurl-related flags. What was the command line used
to link libR.so somewhere above in the log? I think it's not being
correctly linked with libicu, but since shared libraries are allowed to
have undefined imports in them, this is only found out later, when
linking the R.bin executable.

With libcurl installed from conda, what do the following commands print?
curl-config --built-shared
curl-config --static-libs
curl-config --libs

It should also be possible to override the path to curl-config using
the CURL_CONFIG environment variable.
