<p class="MsoNormal">Hello.<o:p></o:p></p>

<p class="MsoNormal">Until some days ago I was using packages MPICH and PETSc which were both downloaded and installed by me, locally in my Linux environment. I could then download and install SLEPc without issues.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Recently I had to change to another environment where MPI and PETSc were already pre-installed. I have access to them through a mounted disk. I then tried to install a SLEPc in my local disk using such mounted packages, and I am getting
the following error right away:<br>
