make[1]: *** [UDUNITS.o] Error 1
I suspect that the compilation environment for your perl(1) utility is
incompatible with the compilation environment of the UDUNITS package.
Do you need the perl(1) interface to the UDUNITS package? If not, then you can
avoid this problem by omitting the perl(1) interface by setting the environment
variable PERL to the empty string before executing the configure(1) script.
For example:
$ make distclean
$ PERL='' ./configure ... >configure.log 2>&1
If you need the perl interface, then you must use the compiler that was used to
build the perl(1) utility. Execute the command "perl -V". Then set the
environment variable CC to the pathname of the compiler that was used to build
the perl(1) utility. For example
$ perl -V
...
$ make distclean
$ ./configure ... CC=gcc >configure.log 2>&1
