errors in installation manual page

hi Natsuhiko,

It seems that there are errors in the installation manual page of rasqual githubpage.

export CFLAGS="-I/path/to/your/CLAPACK-*.*.*.*/INCLUDE -I/path/to/your/CLAPACK-*.*.*.*/F2CLIBS -I/path/to/your/gsl-*.*"
export LDFLAGS="-L/path/to/your/CLAPACK-*.*.*.* -L/path/to/your/CLAPACK-*.*.*.*/F2CLIBS -I/path/to/your/gsl-*.*/lib"

where -I/path/to/your/gsl-*.* should be -I/path/to/your/gsl-*.*/include in CFLAGS, while -I/path/to/your/gsl-*.*/lib should be -L/path/to/your/gsl-*.*/lib in LDFLAGS, the installation was successful after I changed like this.
