[ncl-install] Runtime error with NCL 6.2.1 on OS X 10.6.8 after upgrade

[Chris Waigl]

All,

I upgraded NCL from 6.1.0 to 6.2.1 on my Mac (OS X 10.6.8 Snow Leopard) by downloading the precompiled binaries (OpenDAP enabled). Everything appears to be working fine, until I try to print to png files. Code snippet:

===
outputtype = "png"
...
xwks = gsn_open_wks(outputtype, "filename")
=== 

The error appears the first time plot is called on this workstation. Error message:

===
dyld: lazy symbol binding failed: Symbol not found: ___emutls_get_address

The file /usr/lib/libSystem.B.dylib does exist:

The error does not occur if I print to pdf instead of png. It also didn't occur with 6.1.0 before the upgrade. 

Has anyone seen anything like this? Is this a problem with my environment or with the way the executable is compiled? 

Thanks,
