pcre problem with compiling on Linux

Hi guys! Did a quick search, but didn't really find this specific problem. I've tried compiling the game some time ago, the resulting binary starts but crashes when trying to start new game:

Segmentation fault
./ivan(_ZN18globalerrorhandler22DumpStackTraceToStdErrEi+0x38)[0x59fcb7da3076]
./ivan(_Z12CrashHandleri+0x19)[0x59fcb7d2e2c2]
/lib/x86_64-linux-gnu/libc.so.6(+0x42520)[0x7360fc042520]

./ivan(main+0xa91)[0x59fcb7d2edae]

./ivan(_start+0x25)[0x59fcb7ae6bf5]

Then I got the most recent pcre-8.45 from the sourceforge, compiled it and installed, then at the end of the IVAN compilation I got this warning:

/usr/bin/ld: warning: libpcre.so.3, needed by /lib/x86_64-linux-gnu/libglib-2.0.so.0, may conflict with libpcre.so.1

and now the resulting binary doesn't start and the error message is:

./ivan: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory

What should I do?

I'm using Ubuntu with 6.8.0-60-generic kernel
