Porting cesm 1_2_0 to Linux box with gfortran 4.8.1 and perl 5.18

I successfully compiled the ICRUCLM45 testcase on my laptop, and want to report the following modifications:1) my laptop system has no gmake executable, so I set the GMAKE in env_build.xml to the value "make". BUT in some of the csh shell script the hardcoded gmake is used instead.2) my laptop has installed perl 5.18, which requires a fix in some of the perl packages(found solution on http://perltraining.com.au/tips/2013-06-04.html)[...]qw(...) can no longer be used as parentheses You can no longer write:foreach my $foo qw(a b c d e) { ... }you must now enclose the qw() within parentheses:foreach my $foo ( qw(a b c d e) ) { ... }[...]3) my laptop has gfortran 4.8.1 which chockes on some ESMF related code for a namespace clash with MCT. The fix required renaming of a dummy argument in some source files.4) Solution for this is not included, but the CRU dataset is not downloaded from svn repo without manually adding part of the data path in the datm.input_data_list:[...]/atm_forcing.datm7.cruncep_qianFill.0.5d.V4.c130305/.......SHOULD read for me[...]/atm/datm7/atm_forcing.datm7.cruncep_qianFill.0.5d.V4.c130305/.......
