I am unable to set up a pipeline pilot server because the apache server refuses to start

I am trying to create a new pipeline pilot server on red hat 7 linux. I have checked that the port I use is free (it is). However when I try and start the server I get the following error


***

./startserver

Any help with this would be appreciated

*****************EDIT******************************

Looking at the install log file I find the following two lines

***
