When installing PHP 5 from source I ran into the following problems and solutions:

sudo apt-get install libxml2-dev

Problem:

During make:
/usr/bin/ld: /usr/local/ssl/lib/libcrypto.a(cversion.o): relocation R_X86_64_32 against `.rodata.str1.1′ can not be used when making a shared object; recompile with -fPIC
/usr/local/ssl/lib/libcrypto.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
make: *** [libphp5.la] Error 1

Solution: Go back and reinstall openssl with ./config enable-shared as per this answer and not sure if it mattered but i also did ‘apt-get install curl’ at this point.

Next Problem:
/usr/bin/ld: cannot find -lltdl
collect2: ld returned 1 exit status
make: *** [libphp5.la] Error 1
Solution:
as per this page we try this:
sudo apt-get install libtool
sudo apt-get install libdbd-mysql

and we’re up and running with our chosen options!
