Miscellaneous problems upgrading to PARI 2.5.3 problems on a Mac 10.8

["Ewan Delanoy" <ewan.delanoy@gmx.fr>]

  Hello all,
 
 
   I am currently trying to upgrade the PARI-GP version on my Mac to the latest stable version, but as I expected I am encountering miscellaneous problems :
 
 
Executing the instructions of the  INSTALL file, â./Configureâ and âmake allâ work without problems, but âmake benchâ appears to become stranded (more than 15 min, after which I decided to abort the process) with the following output :
 
 
MacBook-Pro-de-Ewan:pari-2.5.3 ewandelanoy$ sudo make bench

And this partial upgrade has corrupted my GP interpreter : now it displays a strange behavior exemplified below :
