ncl 6.1, ESMF, Linux and OSX

I'm upgrading to 6.1 (from 6.0) on my Linux (Redhat 5 and 6) and OSX
(10.6 and 10.8) systems and have run into some questions/problems.

1a. On Linux, I'm using the 686 Debian (non-opendap) binary because
there's no 686 Redhat version. I have a pretty good idea that this is
behind the problem I'm seeing but bear with me a moment. After install,
I'm using ESMF functions to try to do a regrid. The two
curvilinear_to_SCRIP calls are fine, but then the ESMF_RegridWeightGen
call fails when it can't find libcurl_gnutls.so.4. I don't have that
library and, from a brief look around, it seems this is only distributed
in Debian. If so, then the fact I'm using a Debian binary on a Redhat
system is a perfect explanation for the error. But my real question is
*why* is this library needed for the weight generation call? Seems odd.

1b. I'll actually be migrating my Linux boxes to Fedora in mid-December,
probably to x64, but I'd like to know that I won't run into similar
problems with missing libraries if I use the RH x64 binary. I know RH
is "spawned" from Fedora so wouldn't expect problems but having a
Fedora-specific binary available would be terrific.

2a. On OSX, I have a 10.6 machine that I'll be upgrading to 10.8 but
not soon enough for the work I need to do now. Would it be possible to
have a 10.6 binary created? Or is there any reason the 10.7 binary
wouldn't work on 10.6? I've already updated to gcc 4.7 to avoid the
problems with that being too old that were recently mentioned on
ncl-talk, but there might be other issues.

2b. The binary installed fine on my 10.8 laptop but I've run into some
weirdness with creating the weights file in one combination of
curvilinear grids -- but I'll use ncl-talk for that question!

Thanks,
Dave
