./configurebecause I was getting compiler errors due to the SUNWsprot and SUNWsprot Sun OS packages not being installed.
After getting them installed on the server I tried to run the ./configure again and this time although the compile process went a little further, it stopped after throwing the following errors.
checking how to run the C preprocessor... /lib/cpp
configure: error: C preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details.
