[netCDF #QVK-623215]: Problem compiling netCDF.pm

Joe,

> I re-made the netCDF library using -fPIC by setting CFLAGS in my

The symbol "curl_easy_getinfo" is part of the "libcurl" library, which is used 
by the OpenDAP library. If the "libcurl" library exists on your system, then 
add its parent directory to the LD_LIBRARY_PATH environment variable and try 
the "make test" again. Otherwise, you'll have to install that library via, for 
example, the command "yum install libcurl".
