The file "make.log" contained the following:
...
making `all' in directory /Users/cmertens/NCEP/udunits-1.12.4/src/udunits
make[1]: Entering directory `/Users/cmertens/NCEP/udunits-1.12.4/src/udunits'

Apparently, your math functions aren't in the C runtime library.
They're probably in the "m" library. Try the following:
1. Go to the top-level source directory.
2. Execute the command "make distclean".
3. Set your environment variables as before.
4. Set the environment variable "LD_MATH" to reference the math
library, e.g.,
LD_MATH='-lm'; export LD_MATH
You can use the "nm" utility to verify that the "m" library does,
indeed, contain the missing math functions, e.g.,
nm -g /usr/lib/libm.so | grep floor
5. Continue with building the package as before, starting with executing
the "configure" script.
