This problem usually exist in solaris 5.7

libtool[4766]: : is not an identifier
make: *** [subversion/svn/svn] Segmentation Fault. (core dumped)

Many people suggested to compile it as static link, then the problem will be solved. I have tried but without success. So that i start debug the compile code, lastly i found the problem is caused by ksh.

Solution:

1. do configure as usual
2. replace all ksh to bash or sh in Makefiles and libtool
3. make

P.S. becareful of compile neon, db4, openssl, expat, apr, apr-util for solaris. It seems that gcc < 3.0 have some bugs in solaris system, you better compile them with shared flags
